John Carpenter’s Assault on Precinct 13 is a taut urban siege thriller where a nearly abandoned police station becomes the target of a brutal street gang. With only a handful of cops and criminals inside, the survivors must band together to fight off relentless attackers. Mixing western-inspired standoff tension with gritty 1970s exploitation style, it has become a cult classic.

An LA gang's revenge-fuelled killing spree leads them to a half-abandoned police station in the throws of closing down. Under siege with power and phone lines cut,a lone cop and his skeleton staff recruit a condemned killer from the cells in a desperate battle to survive the night. As the gang close in the tension escalates to boiling point in John Carpenter's brutal and unrelenting cult classic.
