Miriam Hopkins plays a showgirl who witnesses a gangland slaying. Bing Crosby and Elliot Nugent are somewhat over-aged Princeton University students who agree to hide Miriam. They disguise her as a boy (a remarkable achievement) and manage to pull the wool over the eyes of the dean (Henry Stephenson) and even the dean's daughter (Kitty Carlisle). Before the killers are vanquished and Hopkins' life is out of danger, Crosby gets to introduce the hit song "Love in Bloom," which ever after would be associated not with Crosby but with Jack Benny. Based on the Broadway hit by Howard Lindsay, She Loves Me Not was remade in 1942 as True to the Army with Judy Canova, and again in 1955 as How to Be Very, Very Popular with Betty Grable.
