The two merrymakers Cartahu and Bailladrisse sail together on a cargo ship. When customs officers come aboard to conduct a search, Cartahu is unaware of a drug dealer's accomplice, who hides the box of narcotics in Cartahu's bag, which has already been visited. Unsuspecting, the two comrades go ashore, taking the precious box with them. At the hotel, by mistake, their luggage is given to another person. To recover the merchandise, the traffickers pursue the two friends, who nevertheless manage to have the whole gang arrested; and, after being tempted by pretty women to live with them, prefer to set sail for new adventures.
