An ex-Navy seal (Mehcad Brooks), his girlfriend (Serinda Swan) and their friends head out on a road trip to New Orleans. The group decides to stop at a roadside convenience store owned by Chopper (Sid Haig), who tells them the tale of Lockjaw, a fabled god-like creature who is half-man, half-alligator.

When Max, who is recovering from a traumatic accident, takes a job as a nighttime security guard, he begins to see visions of a young mysterious woman in the store's mirror.
