Luke Downing meets a runaway girl in his native town of Garnerville, New Hampshire, dominates her through the use of drugs, and then offers to set her free if she'll help him blackmail two fishermen who visit nearby Garner Lake each year. Convinced that Downing isn't going to keep his word, the girl agrees to his plan but double crosses him in a shocking way that leads to his downfall.
When the two fishermen return to the lake with their wives after the girl sabotages Downing's plan, he makes them his prisoners in a remote cabin where he plans to humiliate and torture them before he kills them.
But when Sheriff Jeff Parker and his girlfriend Molly Hutchison learn of Downing's intentions, they thwart his plans.
