||Mary bets fellow actor Jack she can pass for a WAC (Women's Army Corps) and fools Captain Hal Richards. He asks her for a date. They fall in love, but Mary is sorry she deceived him, because his late sister was a WAC and he respects Mary for enlisting. Hal is upset when he learns the truth. Mary quits her movie acting job, joins the WACs for real, and is reunited with Hal.
