When Sen. Reynolds urges his daughter, shallow society maven Jo McBain (Rosalind Russell), to join the Women's Army Corps, she enlists under the belief that she'll be given special privileges - like a Paris transfer for a rendezvous with her new flame, Lt. Col. Sky Fairchild (William Ching). But when the Army treats Jo like a regular private, she is outraged. Meanwhile, pinup model Clara (Marie Wilson) joins the service to gain respect, and the two women form an unlikely friendship.
