Synopsis:

Roberto, a Naval Academy cadet, embarks on a flirtatious friendship with Claudia, the girlfriend of Paolo, a marine officer. Paolo warns Roberto that if he really wants to participate in the next "Mediterranean Cup" regatta, his friendship with Claudia must end. Roberto is torn, but in the end takes part in the race, his team winning only thanks to his daring manoeuvre, which Paolo tries to take credit for. During the celebrations, Claudia abandons Paolo and races to the port where Roberto is about to leave as skipper in another international race.
