In the seaside town of Canvey Island, we meet Charlie, an 8-year-old boy with a great imagination. He spends his school summer holidays in isolation, playing with his toys and too afraid to leave his room. One fateful day he becomes so hungry he must venture downstairs and into certain danger to retrieve food. It is on this mission where he comes face to face with his greatest fear; his Zombie Parents! And his true adventure begins!
