The forest has always been there, and the high hedge around it has stood since Roman times. No one remembers anymore why the hedge was built, and bit by bit, as houses and modern life advance, the ancient barrier is being torn down. Slowly, creatures that have been trapped within for centuries are creeping through the gaps in the wall, hungry for revenge for their long imprisonment. As murder and horror spread through the nearby town of Hedge End, a stranger arrives, eager to give the residents a May Day celebration they will never forget.
