Stetson's Are Cool

Having not seen The Doctor for a couple of months, Amy Pond and her husband Rory become aware of his recent exploits in history. A blue-coloured envelope (with the number 3 printed on the back) is then delivered and inside they discover is a date and time along with a set of coordinates that lead the couple to Utah in the United States of America. Meanwhile, River Song, who is in prison, also receives a blue envelope (with the number 2) which prompts her to make a break for freedom.

When Amy and Rory arrive at the date, time and location stipulated in the envelope they rendezvous with The Doctor and River Song. From The Doctor’s perspective, it has been several centuries since his last adventure with Amy and Rory (he left them when he was aged 908 and is now 1103). The Doctor also now carries a diary identical to the one carried by River Song, and it is apparent that River Song and The Doctor have shared many adventures together as the two time travellers compare notes at a diner. The Doctor then takes the group on a picnic to a nearby lake, called Lake Silencio, where he tells them he is taking them on a trip to ‘Space 1969’. However, while they are there Amy sees a mysterious figure in the distance, but it then vanishes and Amy immediately forgets what she has just seen. The others though do not see a thing.

Shortly after arriving at the lake the picnickers are also joined by an older man named Canton Everett Delaware III, who had also received an envelope (with the number 4). Suddenly, a figure in a space suit emerges from the lake, and The Doctor warns the others to stay back and not interfere while he goes forward to talk to the space man. The Doctor appears to know who is inside the space suite and it raises its visor. Unable to hear what is being said between them Amy, Rory, River Song and Canton Delaware watch The Doctor lower his head. Then before anyone can react, the astronaut lifts its arm and shoots The Doctor twice. This triggers The Doctor to start to regenerate. But then a third shot is fired from the astronaut which disrupts the regeneration process and kills The Doctor. The astronaut then retreats back into the lake, leaving The Doctor’s companions stunned and horrified.

The Doctor Regenerating

Amy is distraught at what she has just witnessed. River Song then explains that they must dispose of The Doctor’s remains as there are many races in the universe that would exploit a Time Lord’s genetic material and the group, using a can of gasoline brought by Canton Delaware and a canoe found nearby, give The Doctor a Viking-style funeral. Still in a state of shock Amy, Rory, and River Song return to the diner where they discuss the sender of the envelopes. It is then that River Song realises that there must be 4 envelopes sent by The Doctor because the envelope with the number 1 printed on it is missing. As they ponder who the first envelope could have been sent too a younger version of The Doctor - now aged 909 - emerges from the restroom, revealing he also was given an envelope (with the number 1). Hesitant to tell The Doctor of his pending death, they explain the situation so far, and The Doctor uses Canton Delaware’s name and ‘Space 1969’ in the TARDIS’s computer. This results in them materialising in the Oval Office of the White House in 1969.

After making the TARDIS invisible they watch as President Nixon takes a call from a mysterious young girl named ‘Jefferson Adams Hamilton’ asking for help while a younger Canton Delaware looks on. The Doctor reveals himself and gains Canton Delaware’s trust, convincing President Nixon to give him five minutes to locate the child. While he works out her location, Amy again sees a mysterious figure, and not feeling well she excuses herself to a restroom. There the figure waits for her, and kills an innocent woman despite Amy’s pleas. Amy then realises the alien figure is wiping her memory of her encounter and so takes a photo of the alien on her mobile phone. She then escapes from the restroom and again forgets her encounter with the alien creature.

The Doctor Being Shot

Amy then returns to the Oval Office, arriving just as The Doctor finds the young girl’s location - a building near Cape Canaveral, Florida on the intersection of streets named ‘Jefferson’, ‘Adams’ and ‘Hamilton’. The Doctor and his companions leave in the TARDIS, followed closely by a curious Canton Delaware. In the building, they find pieces of a space suit as well as ancient alien technology. River Song and a reluctant Rory explore a vast network of tunnels under the building and River Song discovers that they spread throughout the planet. They also discover, separately, the same alien creatures that Amy had encountered. And like Amy they instantly forget seeing them. River Song and Rory eventually come to a control room unaware that they are being surrounded by more of the alien creatures.

Meanwhile, above ground, The Doctor, Amy, and Canton Delaware hear the cries of the young girl. As Canton Delaware gives chase, Amy realises she must tell The Doctor something as they follow. But before Amy can say anything they find Canton Delaware nearby, unconscious. Amy then finally announces to The Doctor that she is pregnant. But before he can react, the astronaut appears, opening its helmet to reveal the young girl. Without warning, Amy takes Canton Delaware’s gun. Realising what she is about to do The Doctor questions her - for which Amy replies ‘saving your life…’ as she fires the gun at the advancing astronaut.

Three months then pass in which The Doctor, Amy, Rory and River Song attempt to track the alien creatures - recording each sighting on their arms and faces. They are eventually reunited with Canton Delaware, who had been pretending to work against them. The Doctor plants a communication device in each of the group’s hands to record audio of meetings with the alien creatures.

The Silence

While The Doctor alters a part on the command module of Apollo 11, Canton Delaware and Amy visit an orphanage, hoping to find where the young girl in the spacesuit was taken from. There Amy discovers a nest of the alien creatures, and a photograph of her and a baby amongst pictures of the young girl. The young girl then appears with the alien creatures, and Amy is abducted. Arriving too late to help Amy, The Doctor and his allies find her recording device. Canton Delaware is able to shoot and wound one of the alien creatures, and from it The Doctor discovers the alien creatures are called ‘The Silence’, a group he was warned about by several of his foes in his recent adventures. Analysing the now-empty space suit, River Song realises that the young girl possesses incredible strength to have forced her way out of it, and that the suit’s advanced life-support technology would have called the President as the highest authority figure when the girl got scared. Meanwhile Canton Delaware interrogates the captured Silent in the Area 51 prison, who mocks humanity for treating him when they should ‘kill us all on sight’. Canton Delaware records this using Amy’s mobile phone.

The Doctor then uses Amy’s communication chip to track her location, and the TARDIS materialises in the Silence’s control room. As River Song and Rory hold the Silence at bay, The Doctor shows them a live broadcast of the moon landing. As they watch, The Doctor uses his modification of the Apollo command module to insert Canton Delaware’s recording of the wounded Silent into the footage of the landing. Because of this message, the humans start turning on the Silence whenever they see them. Amy is freed and they all return to the TARDIS, while River Song kills all the Silence in the control room.

River Song refuses The Doctor’s offer to travel with him, returning to the Stormcage prison in order to keep a promise. Back in the TARDIS Amy cannot quite remember seeing her picture in the orphanage and now thinks she is no longer pregnant. As the trio set off, The Doctor discretely uses the TARDIS scanner to attempt to determine if Amy is pregnant - but the results prove inconclusive.

Six months later, in an alleyway in New York City a trap comes across a little girl. The girl says she is dying, but claims to be able to fix it. Then before the tramp’s eyes, she starts to regenerate.
