Friends Alberto and Jorge, who work together in an insurance company and live in the same building, are married to two sisters (Elsa and Alicia). When they go on vacation to Mar del Plata, Alberto and Jorge decide to enjoy their "single life". In addition to this, they have to fulfill a duty entrusted by their boss: to find the revue theater entrepreneur Félix Sagastume, to sign an insurance contract. It is in a canteen where they go to look for him, and there they meet two aspiring vedettes (Zuzú and Bibí), who confuse them with important businessmen and see in them a possibility of achieving fame.
