Plot

On an ocean liner sailing from New York, John Bowman lifts his bride Ruth over the threshold of cabin B16, where Anna Quinn, a stewardess busy with finishing touches, greets them and withdraws. Ruth and John have had a whirlwind courtship of just 4 weeks while Ruth has been unsettled by her father’s recent death. John suggests Ruth go on deck to enjoy the ship’s departure while he takes 15 minutes to see the purser to deposit money for safekeeping. As Ruth waves to the crowd in excitement, fellow passenger Kay Prentiss asks Ruth who is seeing her off. Ruth replies that she is waving to no one in particular, as she is traveling with her husband. After John fails to meet her for over an hour, she learns from the purser that he has not been there.
