Tempted

Charlie LeBlanc (Burt Reynolds) is an older wealthy man married to a much younger woman, Lilly (Saffron Burrows). He doesn't completely trust her, so to test her fidelity, he pays a handsome young man (Peter Facinelli) $10,000 to seduce her and another $40,000 if he is successful. Things go as planned until Lilly finds from another source about the scheme and decides to teach her husband a lesson. (Summary by Marinaki)
