As a kickboxing cop, Marlie Franklin protected the citizens of Houston, and as a young single mom, she kept her teenage son out of trouble. However, when a dying witch curses her at a bust, she begins to attract monsters wherever she goes. One disguises itself as an Internal Affairs officer and causes Marlie to lose her badge, forcing her to leave town in search of work.

Then, as the new deputy for Lockwood, Texas, Marlie discovers that mystical evil has rooted itself in the small town, with a gang of bikers casting spells to keep control. When she refuses to back down, her son could lose his life. Can Marlie learn to use the curse within her for good, to cure the corruption of Lockwood?
