Mrs. Markham strongly objects to her husband even looking at another woman and does her best to keep him at her side. While on an ocean voyage she is obliged to leave him because of seasickness. Markham takes advantage of this to slip away and join a party of girls on the ship. He gets a friend to occupy his seat and to wear his coat, so that if his wife looks in that direction she will think him still in his place. Mrs. Markham does look in that direction, but comes along also. She finds the friend, who she berates furiously. Then, going in search of her husband, she acts so frantically that the ship's doctor thinks she is insane and has her strapped down. Hubby comes along and effects her rescue, but not before he has given her time to think over her position and realize the foolishness of her conduct.
