The owner of a factory that produces flavor extracts, Joel Reynold seems to have it all, but really doesn't. What's missing is sexual attention from his wife, Suzie. Joel hatches a convoluted plan to get Suzie to cheat on him, thereby clearing the way for Joel to have an affair with Cindy, an employee. But what Joel doesn't know is that Cindy is a sociopathic con artist, and a freak workplace accident clears the way for her to ruin Joel forever.
