Starring Jack Lemmon, Shirley Maclaine, and Fred McMurray, with director Billy Wilder, the film follows C. C. Baxter (Lemmon). He is a young man working in a large corporation that is very difficult to get ahead in. His only chance of moving up is through loaning his apartment to company executives so they can entertain their lady friends. This set up causes him constant inconveniences and leads to complaints from neighbors. One of these complications involves a elevator girl from work (Maclaine) who was left sleeping in his bed. Soon Baxter must figure out how to nurse her to health and cover for the executive who left her. During the process he slowly feels himself falling in love but it all ends there when she is to be married to the recently-divorced executive. Finally, finding his backbone, Baxter quits his new high-level job and eventually reunites with his love. Wilder and Lemmon teamed up again following Some Like it Hot and this one is pretty good movie-wise!
