Tom (Daniel Lawrence Taylor) and Suze (Esther Smith) are both 19. When nuclear bombs start falling, they have sex. Unfortunately, they then survive.

Eight years later, they’re wandering the wasteland where England used to be. They’re joined by Laura (Jessica Emily Rose), the child they conceived on the night of nuclear war. They end up at a camp of survivors run by Oscar (Jack Whitehall), where it turns out that surviving a lack of food and water is merely the start of their problems.

Cockroaches is a post-apocalyptic comedy about one family trying to survive in a wasteland full of cannibals, perverts and one insufferable ex. Our heroes struggle with boredom, fear and the ethics of cooking with their own body fluids.
