When the zombie apocalypse is unleashed in Birmingham, sisters Kat and Jo, together with unlikely travel companions Sunny and Amar, must flee for their lives... by canal boat.

Jo has just returned from a season as a club rep and has decided to move back in with younger sister Kat, a computer game addict who buys into every conspiracy theory around. Jo struggles to take her sister seriously when Kat claims the zombie apocalypse is real and happening, right now... in Birmingham.

Alongside gym bunny Amar, the upbeat and ready to face things head on character and his oldest friend Sunny, a wannabe misanthrope who'd rather sit out the apocalypse from the comfort of his sofa, Kat, Jo, Sunny and Amar find themselves trapped together on board Dorothy, a narrow boat on the Grand Union canal.

As they journey along the canal in their tightly packed living quarters, friendships develop, alliances form, arguments occur and romance blossoms. Along the way, they realise there is no escaping the problems of everyday life, even in a zombie apocalypse.
