Fussy, minor romantic melodrama/thriller with silly plot twists. Successful software exec Peter (Neeson) and his longtime wife, upscale shoe designer Lisa (Linney), live with their daughter Abigail (Garai) in Cambridge, England. Lisa apparently disappears after dropping hints about marital infidelity and Peter learns by snooping on her computer that she's having an affair with Ralph (Banderas), who lives in Milan. Jealous, Peter heads to Italy, befriends Ralph over chess games in a local cafe, and tries to press him for details on the affair without divulging who he is.
