Still in Europe,the Ricardos and the Mertzes decide to make the trip from Italy to the French Riviera by bicycle. The journey is painful enough for Lucy (Lucille Ball), who hasn't done all that much biking since her childhood (and who, of course, encounters the usual slapstick complications en route), but the pain really intensifies when she discovers that she's left her passport in her suitcase, which has been sent ahead to their French hotel room. Unable to convince the French and Italian border guards to bend the rules for her, Lucy is sure that things just simply can't get any worse -- but it turns out they certainly can.
