In a seemingly amicable agreement, Colbert hops a train to Palm Beach where divorces come easy. Desperate to escape a group of obnoxious millionaires on the train to Florida, Colbert hides out in a sleeping car where she meets, unbeknownst to her, one of the world's richest men (Rudy Vallee) who is relentless in his attempt to romance her.

Upon their arrival in Palm Beach, Colbert is met by her husband who has come to claim her back only to find that Vallee's man-crazy sister (Mary Astor) is after him! The foursome's story unfolds through intensely humorous dialogue, flirtatious situations and a splendid soundtrack.
