Actress Carol Adams retires from the theater when she becomes engaged to businessman Gregory Davis, but is increasingly frustrated by Greg's unwavering devotion to his business. Tired of being ignored, Carol leaves her engagement ring with Greg's secretary, Sarah Anderson, and flies to Mexico City to repair her broken heart and visit her friends, Anita and Arturo Martinez. On the plane, Carol meets Ramon Carranza, a handsome singer and movie star who is wildly popular in Mexico. Anita and Arturo, who are friends with Ramon, invite him to accompany them on their tour of Mexico, which they hope will take Carol's mind off her disappointing romance with Greg. Carol is at first annoyed by Ramon's flirtatiousness, but eventually is charmed by his sweet and lighthearted nature. Meanwhile, back in New York, Greg is anxious about Carol's disappearance, and when Sarah tells him that Carol left because of his neglect, he decides to follow her to Mexico City and win her back. While Carol is visiting many interesting and historical sites with her friends, Greg travels by train to Mexico. During his journey he meets sophisticated American divorcee Eve Parker, whose own marriage broke up due to the neglectful ways of her businessman husband. Eve accompanies Greg to a concert attended by Carol and her friends, and at dinner afterward, acts as if she and Greg are romantically involved when Greg reacts jealously to Ramon's attentions to Carol. Back at their hotel, Eve persuades Greg to learn to rumba and speak Spanish to help him appear more attractive to Carol. Greg takes to his lessons so well that Carol is soon amazed by his new, carefree and relaxed demeanor, and Eve also begins to fall in love with him. As the group travels through Cuernavaca and Taxco on their way to Acapulco, however, Eve realizes that Greg still loves Carol, and begins to flirt with Ramon so that Greg will have more time alone with Carol. Carol begins to worry about Greg's business, as he has secretly told Sarah to send him a series of increasingly urgent telegrams, which he then pretends to ignore in order to devote himself to Carol. Carol is also still jealous of Eve, but finally, while the band of travelers are enjoying the beauties of Acapulco, she reconciles with Greg after he receives an "urgent" phone call from Sarah, who tells Carol that Greg has lost many important contracts due to his absence. Carol begs Greg to return to New York with her, and the reformed businessman takes her in his arms and informs her that his firm is running smoothly, and that he concocted the ruse to win her back. Greg, who has purchased a vacation home in Acapulco, promises Carol that he will balance business with pleasure from now on, and the happy couple wave to Ramon and Eve, who have also reached a romantic conclusion.
