Jenny wants to take over the family auto shop business when her Dad retires. But her father does not believe that she belongs there and plans to leave the company to her knucklehead brother. Determined that she can do the job, she gets a job in one of her father's stores and disguises herself as an ordinary person. There she meets and falls in love with one of the repairmen. She brings the man home to meet her folks, but during the evening the family safe is robbed, and all signs point to her new boyfriend. But did he really do it?
