On arrival at Boston Harbor, he learns his ship has broken down and is being towed to New York for repairs. Hastily, he decides to stow away on a freighter to catch up to his disabled ship. But to gain access to the ship unnoticed, he kidnaps its sole passenger, Katherine Jason, the daughter of the ship's Captain.
