A heist goes horribly wrong when a gang of small time, South London criminals shoot a police officer dead by accident, inside a Post Office.

From there they flee with half of the country’s police force on their trail.

En-route to their getaway destination, they discover an old, remote, manor house, unaware of the unimaginable horror that awaits them, in the shape of a huge, disfigured axe wielding maniac, known as Damon.
