Upon returning for his vacation in Nassau, Sky Ames is anxious to introduce his new fiancée, Linda Bronson, to his best friend, Jeff Holland. Much to Sky's dismay, Jeff and Linda fall in love over lunch and a few days later, decide to elope. On their way to Niagara Falls, Jeff stops to deliver some business papers and finds himself detained at his client's office for the rest of the afternoon. As a result, the impatient Linda decides to call off their engagement and leaves, with Jeff following her in a cab. When both their taxis are stopped for speeding, the policeman escorts them to the judge to be married. Soon after their nuptials, the honeymoon comes to an abrupt halt when Jeff becomes so preoccupied with his advertising business that he neglects his bride. On the eve of the newlywed's vacation cruise, Jeff is called away to a business meeting and misses the boat, prompting Linda to file for a divorce. Jeff becomes so despondent at the loss of Linda that Sky steps in to resuscitate the union by administering a potion developed in his company's laboratory that will make the unhappy couple forget everything that happened to them in the last several months. Once the potion works, Linda and Jeff forget they have ever met, are reintroduced by Sky, and fall in love, thus confounding Linda's confused parents when she introduces her "new" fiancé to them. At first puzzled when Jeff's butler addresses Linda as Mrs. Holland on their first date, Jeff likes the idea and the couple decides to elope that night. On their way to the judge's, they are stopped by the same policeman, who insists upon witnessing the ceremony this time. After the wedding, Jeff, Linda and Sky drink a toast, and Linda shocks Jeff by announcing that the newlyweds are already expecting a little addition to their family.
