You, Me and the Apocalypse

Jamie Winton, a bank manager from Slough, is arrested after police suspect him to be the leader of a terrorist hacking group called Deus Ex Machina. After his alibi checks out, Jamie comes to learn that he has a twin brother called Ariel and that his mother Paula adopted him when he was a baby. Jamie also discovers that his wife Layla, who he believed had disappeared during their honeymoon, is alive and was last seen with Ariel.

In New Mexico, Rhonda McNeil, a librarian, is arrested and placed in a maximum security prison for hacking into the NSA. Rhonda is terrified of her new surroundings and inmates but refuses to give up her son, Spike, who actually did the hacking,and faces the rest of her life in prison. Rhonda is saved from a group beating by Leanne, a white supremacist. However, as the apocalypse is announced, a riot breaks out and Ariel appears to hack into the prison system to rescue Rhonda, as well as Leanne who stowed away.

With limited time left on Earth, Jamie declares he is going to find Layla and get her back. Along with his flatmate Dave, Jamie decides that the best way to do this is to find his birth mother who may be able to tell him where Ariel is. Paula gives him an address that was found with Jamie when he was abandoned. Jamie and Dave travel across the country to the address but are taken hostage by a blond woman, who believes Jamie is Ariel.

Meanwhile, in Washington DC, the US government begins to work on plans to stop the comet and save the world. The president seeks the advice of General Arnold Gaines and Scotty McNeil, Rhonda's brother, who specialise in end of the world disasters for the US government. Scotty declares the only way to stop the comet would be if the world pulls their resources together to do so, causing the US to work with its allies and enemies.

In New Mexico, Ariel and his friend Max are excited to meet Rhonda, believing her to be the only person to hack the NSA. During the escape, a suicide jumper falls onto the ambulance they're in and they crash, with Leanne left stuck inside. Ariel, Rhonda and Max leave Leanne behind but Rhonda reveals who she really is and Ariel abandons her and leaves to find Spike. Rhonda then returns to Leanne to help continue their escape.

Jamie and Dave are being held hostage by Skye, one of Ariel's exes, who is heavily pregnant. After threatening them with a nail gun, Skye's water breaks and she releases Jamie and Dave to help her, successfully, give birth. Believing Jamie says who he says he is, Skye warns him not to go after Ariel but gives him the address for where his birth mother now resides in Scotland anyway.

Rhonda and Leanne continue their escape from prison. They try to steal clothes from a house but Rhonda is caught and held at gunpoint by Buddy, a cross-dresser. Rhonda and Buddy bond and Rhonda has the chance to talk to Scotty about finding Spike, who has been taken into custody by his birth father, and Rajesh, her critically ill husband. Believing he can claim a large reward for Rhonda, Buddy phones the police on her, but she is rescued by Leanne who is pretending to be a police officer. At the same time, Ariel meets Spike and "rescues" him from his father.

Scotty and Gaines begin Project Saviour, an operation using the world's finest minds to stop the comet hitting Earth. Gaines discovers that Scotty has been talking to Rhonda but does not give him up as it is revealed they are lovers.

Rhonda, Leanne, Scotty and Gaines escape the compound and board a plane headed for Slough and the bunker, along with Spike and Rajesh.

Meanwhile, Frankie hears voices in her head and rescues Jamie from the bank vault with the recently married Paula and Dave. Celine discovers that she is pregnant with Jude's child and the whole group drive to Windsor to save Layla from Ariel. Layla and Ariel look desperately for Frankie and head to the bunker where they believe she is. However, Ariel lets slip that he is not Jamie and Layla crashes the car and escapes, leaving an unconscious Ariel behind. Layla then stumbles on Jamie and his group and they all head to the bunker together as small meteorites beginning hitting Earth.

One meteorite hits the plane that Rhonda is in, which crash lands in Slough. Rhonda, Scotty, Gaines, Leanne, Spike and Rajesh hijack a truck and drive to the bunker site, getting inside and reuniting Scotty and Rhonda with their presumed deceased mother.

Just outside Slough, Jamie, Layla, Frankie, Celine, Paula and Dave are stuck on one side of the River Thames after the bridge is destroyed by debris. Desperate to get across Jamie, somehow, parts the River Thames, proving to Paula that he is the son of God after all. The group successfully cross the Thames and arrive at the bunker.

However, debris has ruined the front door and it will not lock. The group devise a plan to close the door using the truck Rhonda hijacked, which means leaving someone behind. Rajesh nominates himself to shut the door, telling Rhonda that he is dying anyway and can't survive much longer. All get inside except Rajesh and Jamie, who helps to move the truck while a figure approaches from behind.

Rajesh tells Jamie to get inside, who does so, just as the door closes and locks everyone inside. They sit down and watch the TV to see the inevitable.
