Melinda (Merola Waters) and Dan (Jay Moore) are a disharmonious couple because Dan uses Viagra when having sex with his wife, but not with the waitress he meets. As some people say, the largest sexual organ is between the ears. The film is unfolded by Roger Clink (James Spader), a psychiatrist who has an affair with Melinda, who suddenly breaks into a motel and finds that Melinda and Dan are "regaining their passion". Gradually, their complicated relationship took shape.
