A group of five colleagues working for the same company in Rome are preparing to leave for a prize holiday on the island of Rhodes. Within the group, we find Commendatore Zerboni and the somewhat absent-minded but good-hearted Augusto, who intends to bring a cactus to the grave of his late uncle Michele.
However, what seemed like an idyllic opportunity becomes complicated when it is discovered that Uncle Michele is actually a conman wanted in Rome, who has taken refuge on the island using the fictitious name of Kemal. Misunderstandings and trouble begin to pile up as Zerboni tries to woo his secretary Angela. Meanwhile, Zerboni's wife Fedora makes the holiday even more complicated for everyone because of her severe myopia.
