Beautiful U.S.O. singer and compulsive liar Lorry Jones (Betty Grable) and her best friend leave Montana for war jobs in Washington, D.C. Stopping in New York City along the way, Lorry spins a web of lies, turning herself into a Broadway star to gain the company of handsome war hero Tommy Dooley (John Harvey). Jealous club singer Molly McKay (Martha Raye) suspects Lorry's claims are false and hopes to expose her. The situation worsens when Tommy ends up in Washington at Lorry's new office.
