After a long separation following the death of their son, Alex and Kate meet again on board the oil-tanker Sea Voyager. That same day, Alex rescues thirty adolescent immigrants adrift in the Mediterranean. No country grants asylum, and the manager of the nearly bankrupt ship owner insists that Alex deal with the situation promptly. But each one of his efforts leads to a dead end. And while some members of the crew grow fond of certain teenagers, including Kate who gives motherhood a second chance, the majority feel that their “guests” have overstayed their welcome. Unable to handle the tension and wrapped up in his depression, Alex makes a series of wrong decisions, until he finally finds the courage to rise above the situation.
