A department store where she works is robbed by Eve Sutton and an accomplice, Carl Briggs. A wristwatch they stole is recognized by Eve's sister Joan, who reports her suspicions to Mrs. Briggs, who is Eve's boss at the store.

Joan bumps into Charley Phelps, the store owner's son, who develops a personal interest in her. As an investigation into the robbery begins, Carl Briggs is shot and killed, his mother's body is also found, and Eve and a co-worker, Mr. Grover, are taken hostage.
