August 2015:

The Warehouse (Mike Tucker)

Due to be released in August 2015 is a Seventh Doctor story, starring Sylvester McCoy, called "The Warehouse". His travelling companion Melanie Bush is played by Bonnie Langford.

This story has been written by Doctor Who special effects guru Mike Tucker. It has been directed by Barnaby Edwards and was recorded on the 12th and 13th January 2015.

This story is a future-set satire on the present-day, set in and around a giant parcel delivery facility in space. But there's something decidedly disturbing going on in this deep space packaging facility. What horrors might it be delivering...

Also starring are: Phillip Franks, Dillie Keane, Clara Buckfield, Barry McCarthy, Anna Bentinck and Barnaby Edwards

The Doctor and Mel land in what appears to be an orbiting warehouse, a delivery facility with a dangerously erratic computer.

Whilst Mel is helping with repairs, the Doctor begins to realise that not everything in the warehouse is as it seems. Why do no goods ever seem to leave the shelves? Why are the staff so obsessed with the stocktake? And who is the mysterious Supervisor?

On the planet below, the Doctor discovers that the computer might be the least of their problems – and that they should be more concerned with the spacestation's mould and vermin...

Early September 2015:

Terror of the Sontarans (Dan Starkey and John Dorney)

The Seventh Doctor and Melanie Bush trilogy for 2015 ends in September 2015 with "Terror of the Sontarans", and its writer is a name well known to Doctor Who fans...

Commander Strax himself, actor Dan Starkey, has teamed up with John Dorney to write this a fast-paced sci-fi thriller set on an alien world, with both the Sontarans and The Doctor facing a terrifying alien force.

'Season 24 is a specific 'flavour' of Who', Dan Starkey has revealed. 'I re-watched some stories I hadn't seen since first broadcast. The Season 24 setting allowed me to invent some larger-than-life characters to offset the brutality of the Sontarans'.

'Having acted in a lot of audio drama, I was conscious of writing something that would give the actors something fun to play and the sound designer interesting atmospheres to evoke. Recording was great fun and I'm really looking forward to hearing the finished piece'.

Both Dan Starkey and John Dorney star in this story that has been directed by Ken Bentley. Also starring are: Daniel O'Meara, Jon Edgley Bond, Andree Bernard and John Banks.

Once it was a mining facility. Then later its corridors rang with screams generated by grotesque military experiments. However when the Doctor and Mel arrive on a hostile alien world after detecting a distress signal, the base they find themselves in is almost deserted.

But not for long. Soon the Doctor's old enemies, the Sontarans, have landed, and are searching for the remnants of their previous research team. Before long they uncover evidence of strange occurrences on the planet. Of madness and death.

They are warriors bred for war, strong of spirit and unafraid of death. To fear the enemy is an act of betrayal. Nothing holds terror for the Sontarans.

Until now...

Late September 2015:

Criss-Cross (Matt Fitton)

The second story due in September 2015 is called "Criss-Cross". Written by Matt Fitton and directed by Ken Bentley this story stars Colin Baker as the Sixth Doctor with new companion Constance Clarke.

In this story The Doctor finds himself at Bletchley Park, during World War Two...

The Sixth Doctor will return for a brand new trilogy of audio adventures in September, and this time there's a new companion aboard the TARDIS. Leading Wren Mrs Constance Clarke is portrayed by Miranda Raison (star of Spooks and the 2007 Doctor Who story Daleks in Manhattan/Evolution of the Daleks) and she has a mystery to solve...

The trilogy begins with Criss-Cross by Matt Fitton, which guest stars Alistair Petrie, Hugh Fraser and Robbie Stevens. Also starring are: Paul Thornley and Charlotte Salt.

"Constance first meets the Sixth Doctor at the famous World War II code-breaking facility at Bletchley Park," explains script editor Alan Barnes. "They're trying to crack a mysterious code and unmask a Nazi agent... one with otherworldly connections."

Bletchley Park. Britain's most secret weapon in the Second World War.

Inside draughty huts, the earliest computers clatter day and night, decoding enemy transmissions and revealing intelligence crucial to the country's defence. Leading WREN Mrs Constance Clarke directs her charges to provide vital assistance to the boffins stationed in the Manor House. But a recent arrival among the code-breakers, the mysterious Dr Smith, has attracted the attention of MI5's spycatchers...

Over in mainland Europe, Nazi agents are briefed, covert operations planned, and a German submarine embarks on a very secret mission.

As encrypted radio waves criss-cross the planet, unearthly forces stir. And when certain ciphers are cracked, something will emerge to threaten all humanity, regardless of allegiance...

October 2015:

Planet of The Rani (Marc Platt)

The story for October 2015 is called "Planet of The Rani". It has been written by Marc Platt and is directed by Ken Bentley.

This story stars Colin Baker as the Sixth Doctor with new companion Constance Clarke and where The Rani returns to the site of her worst atrocities...

Siobhan Redmond returns as the Rani hot on the heels of her acclaimed debut in The Rani Elite. Planet of the Rani is written by Marc Platt who wrote 1989's Ghost Light for the Seventh Doctor on television, as well as dozens of popular Doctor Who audio stories.

'The last time we saw her, the Rani was on her way to space prison', Script Editor Alan Barnes has revealed. 'In "Planet of the Rani", she's got a plan to get out and return to the hitherto-unseen world of Miasimia Goria... where one of her worst atrocities is waiting for her!'.

Also starring are: James Joyce, Olivia Poulet, Dominic Thorburn, Tim Bentinck and Chris Porter.

Miasimia Goria was a quiet planet, an ancient world of bucolic tranquillity… until the Rani arrived with ideas of her own.

She planned to create a race of new gods… gods that she could keep on her leash, but those plans went horribly wrong.

Now, she languishes in the high security of Teccaurora Penitentiary, consigned there by her arch enemy and old student colleague, the Doctor.

But the Rani, always resourceful, ever calculating, knows things about the Doctor’s past that he would rather forget. She wants revenge, even if it takes a hundred years… and then she has other unfinished business.

The ruins of Miasimia Goria await…

November 2015:

Shield of the Jötunn (Ian Edginton)

After helming episodes of The Companion Chronicles and Blake's 7, Louise Jameson, who played the Doctor's companion Leela in the 1970s, makes her directing debut on the main Doctor Who range with "Shield of the Jötunn" that has been written by Ian Edginton.

This story, due in November 2015, stars Colin Baker as the Sixth Doctor with new companion Constance Clarke.

Script Editor Alan Barnes has stated that 'Comics writer Ian Edginton - whose name will be very familiar to readers of 2000 AD, among others! has come up with this story, set in the Arizona desert in the near future... amid a howling blizzard, seemingly connected to the unlikely discovery of an ancient Viking tomb'.

The all-American guest cast includes Michael J Shannon, Nell Mooney, James Caroll Jordan and Ryan Forde.

2029 AD. In the desert of Arizona, billionaire philanthropist Dr Hugo Macht is trying to save the world from climate change. But his great project to "scrub the sky clean" with nanoatomic machines grinds to an unexpected halt when his diggers break into something unexpected: a Viking burial barrow containing eight corpses, a mysterious shield, an even more mysterious inscription... and a yet more mysterious traveller in time and space, known only as the Doctor.

And that's not even the strangest part of Dr Macht's day. Soon, it'll begin to snow. Soon, the Doctor and his girl Friday, Mrs Constance Clarke, will come face-to-face with an ancient horror in the blizzard. A Frost Giant, in need of a new body. In need of flesh...

December 2015:

The final release for 2015 is a Seventh Doctor and Ace story, staring Sylvester McCoy and Sophie Aldred, called "You Are The Doctor". This release also includes other stories that have been written by: John Dorney, Jamie Anderson, Christopher Cooper and Matthew Elliott.

Full cast, production and plot details to follow as soon as they have been announced by Big Finish Productions.

January 2016:

January 2016 sees the return of the Fifth Doctor, Nyssa and Tegan Jovanka in a brand new audio trilogy with new stories set during the 1983 season (Season Twenty).

'For the next Fifth Doctor trilogy, we're jumping back to the end of "Arc of Infinity"', script editor Alan Barnes has announced. 'At the moment Tegan rejoins The Doctor and Nyssa on their travels-literally to that exact moment, in Amsterdam in the spring of 1983! That's where Jonathan Morris' "Waters of Amsterdam" begins - in which our reunited trio discovers something nasty in the city's canals, requiring them to make a side-trip to the city's past, to make a house call on the famous artist Rembrandt himself...'.

The gap between the television stories "Arc of Infinity" and "Snakedance" has proven to be rich in opportunities for new adventures to be told. As Alan Barnes has revealed 'What's quite startling about the gap, think, is there's virtually no mention of Tegan's time away-and of course, in the interim, The Doctor and Nyssa have shared a huge number of audio adventures that Tegan has not been privy to! So there's an emotional gap to fill, as much as a chronological one'.

Starring Peter Davison as the Fifth Doctor, Sarah Sutton as Nyssa and Janet Fielding as Tegan this story has been directed by Jamie Anderson.

Full cast, production and plot details to follow as soon as they have been announced by Big Finish Productions.

February 2016:

February 2016 sees the second story that sees the return of the Fifth Doctor, Nyssa and Tegan Jovanka, in a brand new audio trilogy with new stories set during the 1983 season (Season Twenty). "Aquitaine" is written by Simon Barnard and Paul Morris who make their debut in the Doctor Who monthly range.

'The title comes from the name of the colossal spaceship the TARDIS lands on next', script editor Alan Barnes has revealed. 'They're answering a distress call from the ship's computer: its entire crew has gone missing, and it can't remember why! This one's got a bit of a Silent Runningfeel, we think...'.

Starring Peter Davison as the Fifth Doctor, Sarah Sutton as Nyssa and Janet Fielding as Tegan this story has been directed by Ken Bentley.

Full cast, production and plot details to follow as soon as they have been announced by Big Finish Productions.

March 2016:

The trilogy of  Fifth Doctor, Nyssa and Tegan Jovanka stories set during the 1983 season (Season Twenty) is "Aquitaine" ends in March 2016 with "The Peterloo Massacre" - a historical adventure written by Paul Magrs.

'Paul wrote "The Lady of Mercia" for us a couple of years ago', script editor Alan Barnes has revealed, 'but unlike that historical story, this one's got no comedic elements whatsoever. It's set in Manchester in 1819, when a workers' protest at St Peters' Field was brutally crushed by the authorities. It's a particularly bleak, harrowing moment in British history, and it's fair to say, this is a particularly bleak and harrowing play'.

Starring Peter Davison as the Fifth Doctor, Sarah Sutton as Nyssa and Janet Fielding as Tegan this story has been directed by Jamie Anderson.

Full cast, production and plot details to follow as soon as they have been announced by Big Finish Productions.
