A young boy's burning ambition to go to sea is realised when he is offered a place on a vessel sailing to America. He gets drunk at a party thrown by American boys and his ship sails without him. To avoid the authorities, who he thinks will jail him as an illegal immigrant, he goes on the run. He is kidnapped, forced to help in a bank robbery, and threatened with death. He manages to escape his captors, taking their loot with him, but is chased across Texas. Attempted murder, robbery, shipwreck, and the love of a beautiful senorita keep the adventure racing to its conclusion.
