The Bow Bells Care Home is under threat and the McGuires – Andy, Terry, and Katy – need to find some way to keep their Grandfather and his friends in the East End where they belong. But, when you’re robbing a bank, zombie invasions make things a lot harder. And, let’s face it, they need all the help they can get when their bank-robbing experts turn out to be Mental Mickey and Davey Tuppance. As contractors to an East London building site unlock a 350-year old vault of seriously hungry zombies, the East End has suddenly gone to hell and the Cockney way of life is under threat. Equipped with all the guns and ammo they can carry, it’s up to the gang to save the hostages, their Grandfather, and East London from zombie Armageddon.
