Girl Overboard.

A young man is sentenced to prison for a term of eight years, yet he's allowed out if he promises not to get married for those eight years, lest he be forced to complete his sentence behind bars. He goes to live on an old ship in the harbor with an old sea captain. One day a homeless girl is fished out of the water and brought to live on the boat, soon marrying the young man. All is well until his parole officer finds out.
