This charming comedy drama is a triptych about a drifter who exerts an almost magical impact on everyone he meets.

The film deals with Zelida, an eccentric spinster, whose jewellery is stolen. She and her cousin use the insurance money to undertake a cruise from South Africa to Venice. She is completely unaware of the fact that a fellow passenger, an ambassador, actually is a detective. Meanwhile, the robber, his beautiful girlfriend and the looted jewels are on the same cruise ship. In addition, an orphan stowaway is making matters worse.
