It's bedlam in the boudoir when Bob Hope sets his comedic sights on 18th-century Italy. Hope plays Pippo Popolino, a lowly tailor who is suddenly drafted to temporarily impersonate the great and passionate lover, Casanova (an unbilled Vincent Price). Pippo thinks he has the masquerade all sewn up - totally unaware that, due to the real Casanova's shaky financial situation, he is now locked into the role by the romancer's scheming, greedy creditors! Along the way, our great lover manages to woo some lovely ladies (Joan Fontaine and Audrey Dalton) - when he's not dodging spontaneous swordplay or bumbling his way through the finer points of royal etiquette.
