Zara and her bridal party leave their Birmingham council estate for a messy hen do in an isolated Welsh cottage. However, the fun gets derailed by the end of the world. With only their plastic hen do tat, a rapidly diminishing supply of novelty chocolate penises and zero survival skills to call on, how will the women fare against Armageddon?

Forced to break quarantine and venture into post-Apocalyptic Snowdonia, the hens start to piece together what happened in the outside world.

Desperate for food that isn’t the owl meat they’ve been surviving on for nine weeks, they encounter a fearsome radicalised Pilates instructor who’s on a top secret mission, but the hens have a secret of their own though: Having taken captive male stripper-come-entrepreneur Drew, who they believe is the only man to have survived the Apocalypse. The question is: once you’ve got the last man on Earth, what exactly do you do with him?

Amongst the ruins of human civilisation, love blooms in very unexpected places, ethics fall by the wayside, Danny Dyer is a spirit animal offering a spiritual redemption experience for one, and friendships are tested to the limit, including a life or death incident with a carving knife and a Fray Bentos pie.
