The Love Boat - Season 1 Episode 11
Lonely at the Top/Divorce Me, Please/Silent Night

In a Christmas-themed cruise, the captain worries about how to effectively lead his ship but be a friend to his crew as well. A married couple who outwardly appear happy and in love are both desperate for the other person to give them a divorce - and they go to extreme measures to get it. An embittered ex-con boards the ship for a holiday with his wife but also with revenge on his mind for the person who framed him for the crime. A priest brings a group of orphans aboard for the cruise.
