The plot is this: Roland Young and Genevieve Tobin have been married for one year, and they feel as if they are drifting apart in their marriage. They decide that they will take separate vacations away from each other to sort the marriage out. Tobin decides to go on a pleasure cruise, and while aboard many available men begin to hit on her, and she begins to contemplate having a quick shipboard fling with one of the men.
Unknown to her, her husband had gotten a job as a barber aboard the ship in order to keep a close tab on her and who she speaks to.
Later in the voyage she meets Ralph Forbes, who is the most forward of all the suitors they have met. After the fancy dress ball aboard the ship, he asks if he can slip into her cabin and spend the night. After some thought, Tobin decides to leave the cabin door unlocked, and when she is asleep a man slips into the cabin and makes love to her...but it was her husband and not the suitor.
Watch for some funny and awkward dialogue the morning after as Ralph Forbes tries to apologize for not going to her cabin the night before, and Tobin things he is apologizing for a poor performance in the bedroom.
This film is quite remarkable at how frank and sexual the movies could be before the production code came into effect, and if you can get your hands on a copy of this film, by all means watch it and enjoy.
