Evelyn Walsh Warren is named Teacher of the Year and her photo is on the cover of Time magazine, but she is dissatisfied with her uneventful life. That changes when she goes to Reno and inadvertently loses $7000 at the roulette table, mistaking $100 chips for $1 ones. Casino owner Matt Braddock offers her a deal: He will tear up her IOU if she finds out what is wrong with his nine-year-old daughter Diane, who is moping around, not eating and having nightmares. When Evelyn refuses, he suggests they cut cards for the debt. She gets a king, but he tops her with an ace (by cheating). Defeated, she accompanies him to his home in Carmel, California.

Frustrated at her predicament, Evelyn is initially cold to Diane, but after overhearing the child's telephone conversation with her father, Evelyn becomes ashamed of herself and quickly becomes fast friends with her young charge. Soon, Diane is happy, much to Matt's delight. In fact, she is so taken with her new private teacher that she begins maneuvering to set Evelyn up with her father.

Diane becomes frustrated when Kay Stoddard, Matt's old flame, shows up. Undaunted, the young girl manages to steer Kay into some poison oak to get her out of the way. Evelyn is hostile to Matt at first, but gradually warms to him. When they go out fishing on a boat, she secretly disables the motor to spend more time with him. Matt, however, flags down a commercial fishing boat owned by Manuel to take them aboard. Evelyn gets drunk on a seasickness remedy and admits to Matt that she has fallen for him; they become engaged.

Matt sells his casino so his future wife will not be ashamed of him, but he gets a shock when Evelyn tells him that it was all an act. She goes home.

There, she receives a telephone call from Marie, Matt's housekeeper. Diane has run away. Frantic, Evelyn flies to Carmel, where she and Matt blame each other. However, it turns out that Diane (with Marie's encouragement) was just hiding. The little girl gets the two to realize they really do love each other.

TV Guide panned the film, stating "The unbelievable and obvious plot is further hampered by the miscasting of Darnell. Though he directed the film smoothly, Sirk has been quoted as saying he '[had] no feeling for this picture at all,' which is obvious in the final product."^[1]
