Ed Kunkle is a convicted felon tormented by his own demons. Eve Adams is a single woman trying to cope with a tragic loss. Bodie Jameson is the detective looking for answers. All 3 lives intertwine with horrific consequences when their fears come upon them.

Shifting from one pocket to another, from one man's drama to another, a lowly dollar bill, 'one buck' takes us on an odyssey through the heart of a forgotten town in Louisiana.

An American family celebrates their 28-year-old daughter's pregnancy. The celebration is interrupted when a Satanic cult leader, Henrik Brandr, unexpectedly visits their ranch. Henrik offers to pay the family a large sum for ownership of their land. Jacob Richardson, the father, rejects the offer due to the priceless sentimental value of the ranch. Henrik, displeased, begins to put devastating curses on the Richardsons, trying to force them off their land - even if it means murdering them. After suffering unexplainable tragedies, the Richardsons seek help from Marybeth, a white witch high priestess. They soon discover a terrible secret about their house, revealing why their land is so valuable to the cult. They realize they must protect their house from the cult at all costs, and a violent battle between good and evil ensues.
