• Gina Lollobrigida
• Alec Guinness

While his icy wife is away tending to a sick friend, Benedict Boniface (Alec Guinness) has an affair with Marcelle Cotte (Gina Lollobrigida), the pretty but neglected wife of the pompous architect Henri (Robert Morley). When Henri unexpectedly returns, Marcelle and Benedict don disguises and hide out to avoid being caught by her husband. The comedy of errors allows for several sight gags and farcical bedroom situations. Peggy Mount is particularly effective as the dominating wife who makes her husband tremble with fear by her very presence.
