Sex & Sushi(2006)

Monogamy isn't natural, it's just another long con.

Sex & Sushi is a romantic comedy following a sharp-tongued private detective in New York City who makes his living catching unfaithful husbands. Cynical and quick-witted, he's built a career on exposing infidelity to wronged wives. Everything changes when he takes on a new case and finds himself falling for a client. As genuine feelings develop, the detective begins questioning his jaded worldview and the assumptions that have defined both his work and his personal life. The film explores what happens when a man built on skepticism encounters something he can't investigate his way out of: real connection.
