Women in War (1940)

A "good-time girl", raised by her somewhat lax divorced father, finds herself involved in an accidental death, and the only way she's able to get out of it is to volunteer--albeit reluctantly--to be a nurse in the war effort. She travels to England and is assigned to a hospital under a very strict matron. What the girl doesn't know is that the matron is the mother she has never seen.
