When a group of ordinary people learn that an eight-mile-wide comet is on a collision course with Earth, they hunker beneath the town of Slough to watch the end of the world on television.

Comedy-drama about the final days of mankind. Mild-mannered Slough Bank Manager Jamie (Mathew Baynton) is in a rut--albeit a very organized one--consumed by grief for his missing wife. All of that soon changes when he's arrested on suspicion of cyber-terrorism and realizes that, somehow, he must have an identical twin, and that his mum Paula (Pauline Quirke) has some serious explaining to do. Halfway around the world in New Mexico, unassuming librarian Rhonda (Jenna Fischer) enters a maximum-security prison for a crime she didn't commit and reluctantly falls under the wing of unhinged white supremacist Leanne (Megan Mullally). At the Vatican, meanwhile, foul-mouthed rebel priest Father Jude (Rob Lowe) interviews beautiful Sister Celine (Gaia Scodellaro) for a role in his office of the Devil's Advocate. These are just some of the eclectic and seemingly unconnected characters whose lives will start to intersect in the most unexpected ways as news breaks that a comet is on an unavoidable collision course towards Earth and will hit in just 34 days. Some of them are destined to make it to a bunker deep beneath the suburbs of Slough and, as a result, will become the hugely unlikely (and, frankly, somewhat unsuitable) future of mankind.—simonwarn
