Summary

A wealthy Wall Street financier discovers his wife is having an affair with a struggling artist and confronts the lover with a proposition: kill her in exchange for a large payoff. When the meticulously planned murder goes wrong, a tense game of deception, blackmail, and shifting loyalties unfolds. A modern reworking of Hitchcock's Dial M for Murder.
