Pretty Parisienne Ariane Chavasse (Audrey Hepburn) was intrigued that her private eye papa (Maurice Chevalier) had been hired to shadow the aging American playboy Frank Flannagan (Gary Cooper). When she learns her dad's client wants to settle things with a bullet, though, she sets out to covertly warn the at-risk roué, and romantic complications ensue. Billy Wilder's charming nod to Lubitsch co-stars John McGiver, Lise Bourdin. 130 min. Widescreen (Enhanced); Soundtrack: English Dolby Digital mono.
