Concluding the saga begun in Adam Green's hit 2006 thriller, "Hatchet III" follows the vengeful Marybeth (Danielle Harris) as she continues seeking out a way to destroy Victor Crowley (Kane Hodder), a hulking, seemingly-invincible sociopath rampaging through a sleepy Louisiana swamp.

While a heavily-armed team of mercenaries takes to the bayou surrounding Crowley's home, Marybeth finds herself begrudgingly teaming up with a local policeman (Zach Galligan) and his ex-wife (Caroline Williams) - an expert on the maniac who may have uncovered the secret to ending his murderous rampage once and for all.
