Dreamland (Doctor Who)

13 June 1947: a spaceship, trying to escape from two others, is shot down and crashes on Earth near Roswell, New Mexico. Eleven years later in Dry Springs, Nevada, The TARDIS materialises at a diner, and the Doctor meets Cassie Rice and Native American Jimmy Stalkingwolf. He uses his sonic screwdriver to investigate an alien artifact. Detecting that the artifact has been activated, two Men in Black arrive demanding the artifact in question. The Doctor and the others escape, to investigate Jimmy's "space monster". The monster turns out to be a Viperox battle-drone and is destroyed by a rocket from a USAF helicopter which arrives on the scene. The soldiers take them to Area 51 (aka Dreamland). In Dreamland, Colonel Stark locks them in a cell with a gas that will wipe their memories. The Doctor manages to break free, stop the gas, and escapes with Cassie and Jimmy via a ventilation shaft. The alarm sounds and they run into a lab where they find a captured grey alien. After fleeing pursuing guards in a lift they are recaptured at the top of the lift shaft. Colonel Stark is revealed to be working with a Viperox leader named Lord Azlok.

The Doctor, Cassie and Jimmy find themselves in a hangar which contains a spaceship similar to the one that crashed in 1947. The Doctor escapes by piloting the ship. They are pursued by two fighter jets and crash near an abandoned mining town called Solitude. Exploring an abandoned building, Jimmy is pulled into a hole in the floor by a Viperox. The Doctor and Cassie follow and find Jimmy being questioned by Lord Azlok about the Doctor. The Doctor emerges from hiding and confronts Lord Azlok. Lord Azlok reveals that he is only seeking "an enemy of our kind". Before the Doctor can find out the identity of their target, Cassie, who has freed Jimmy, effects an escape by starting a fire with an oil lamp. The group then stumble across a large number of Viperox eggs and are confronted by the huge Viperox Queen, which is laying the eggs. Behind them, their Viperox pursuers are bearing down.

The Doctor, Cassie and Jimmy escape through the mine tunnels in a mine railway cart. When the cart finally exits the mine shaft, the three are greeted by Mr. Dread and the other "Alliance of Shades" android. The four androids are then destroyed Jimmy's Grandfather Night Eagle, who turns out to be familiar with aliens. The group proceed to a cave where a grey alien by the name of Rivesh Mantilax is kept. He tells the story of how his people fought the Viperox and lost years before. After his tale, Colonel Stark enters the cave and thanks the Doctor for leading the army to the alien, proclaiming the Doctor has helped him to save the world.

Stark takes them back to Area 51 – along the way Night Eagle grimly notes, "Men like Stark don't save worlds. All they know is destruction." Rivesh Mantilax is reunited with his wife Seruba Velak and the alien tech found in the diner turns out to be a genetic weapon designed by Rivesh Mantilax to destroy the Viperox. The device can only be used by Rivesh Mantilax's DNA, and he is also the only one that can change the code to attack other beings, hence why Lord Azlok wanted it. Stark intends for the device to be reprogrammed to destroy the Russians, but the Doctor refuses to allow this and snatches the weapon, fleeing to the roof with Stark in hot pursuit. The Doctor, cornered by Stark, ultimately convinces him that his alliance with Lord Azlok and the Viperox will only lead to disaster – the Viperox will at some point betray Stark and conquer Earth (as they have already conquered the technologically superior race Rivesh and Seruba belong to, the US Army would have no chance at all). Stark orders his men to arrest Lord Azlok, but he escapes, declaring that the Viperox will "tear your world to shreds".

The Doctor and Stark run down to the room where Rivesh and Seruba are, but find that Seruba is cradling Rivesh. She reveals that Azlok has mortally injured him and he is dying. However, Seruba says there was something in the ship that could revive him, but Stark says that anything found in the ship was stored in the Area 51 vault, which hasn't been entered for some time as something got loose in there. The Doctor, Cassie, Jimmy, Seruba and Stark arrive at the vault, and the Doctor asks Jimmy and Cassie to find the TARDIS back at Dry Springs. Inside the vault, the Doctor and Seruba go and look for the device they need. Meanwhile, in the Viperox lair Azlok gets the Viperox Queen to release her newly hatched brood, so that they will destroy the whole town. Back in the vault, the Doctor comes across a swarm of Skorpius Flies, a carnivorous alien species that form a group mind. Seruba tells the Doctor she has found the device that could revive Rivesh, but the Skorpius Flies chase after them until the Doctor finds a crate and hides inside. He helps Seruba escape inside the crate by working out how many steps he took on the way in. At the Area 51 base Stark is informed that they are getting reports of Viperox attacks. He orders a row of tanks to block the Viperox off. The Doctor and Seruba shuffle out of the vault inside the crate so the flies won't notice. Meanwhile, Cassie and Jimmy are driving along with the TARDIS on the back of Jimmy's pickup truck when the Viperox burst out of the ground into their path.

Jimmy manages to swerve and drives off while the Viperox chase after them. Helicopters fly over head and fire at flying Viperox. Stark is annoyed that they are losing, when Lord Azlok storms in and tries to get the truth of where the Doctor is. The Doctor and Seruba have escaped the vault and drive a Jeep to the base, where they see that it's under heavy attack. The Doctor is worried about getting in until Jimmy and Cassie show up with the TARDIS. The TARDIS materialises in the room in Area 51 where Rivesh is dying. In the nick of time, Seruba revives Rivesh. The Doctor asks for the device to be activated and Rivesh relishes the thought of killing the Viperox. However, the Doctor warns him not to detonate it, or it will completely wipe the Viperox out. Rivesh remains adamant on revenge, but the Doctor reinstates his beliefs and tells him that no-one should have the power to exterminate an entire species. Rivesh returns the favour of his revival and trusts the Doctor with the device. The Doctor uses his sonic screwdriver on it and then he rushes into the TARDIS and grabs a cable. At that moment, Azlok holds Jimmy hostage at the entrance to the TARDIS, threatening to kill him if the Doctor detonates it. The Doctor says he isn't going to set it off and explains that one day the Viperox will become a peace-loving race. Azlok dismisses this as madness and advances, but the Doctor connects a cable from the TARDIS console to the device and unleashes a deafening soundwave that affects all the Viperox in the area: the Doctor then orders the Viperox to leave Earth and never return. A furious Azlok vows that the Doctor's time will come, though the Doctor dismisses the warning of his impending death, before Azlok and the rest of the Viperox retreat and flee from Earth. After the attack, Stark thanks the Doctor and Seruba and Rivesh leave in their ship. The Doctor leaves the weapon with Stark in case the Viperox ever return, and Stark warns them to keep quiet about the events. The Doctor suggests that Cassie and Jimmy clear up the Viperox mess. As the TARDIS departs, Cassie and Jimmy hold hands.
