To save his job, David agrees to a harebrained scheme: bringing back a mysterious package from South America. He finds himself on a cruise with his ex-girlfriend Tess, his son Leo, and his bumbling, clueless colleague Stéphane, whom David is using to transport the package in his place. Everything goes wrong when Stéphane accidentally opens it: a baby marsupilami appears, and the trip descends into chaos.
