BJ McDonnell directs the third instalment in this series of slasher horror movies starring Kane Hodder as a bayou-dwelling serial killer. After Marybeth (Danielle Harris)'s parents were brutally murdered by the hatchet-wielding Victor Crowley (Hodder) she became consumed with the need to avenge their deaths. Continuing on from the end of 'Hatchet II' (2010) which saw her blow the killer's head off with a shotgun, Marybeth has since been arrested for the murders of the numerous other bodies found at the swamp. Being under the impression that they have their killer, the police are reluctant to believe her claims of a curse that enables Crowley to respawn after being killed. Can she finally convince them of Crowley's existence before he strikes again?
