When her plane-crazy high school sweetheart goes off to join the Army Air Corps, Pam Wright writes him often but is disappointed that he doesn't reply to every letter. She's lonely, hurting from his seeming lack of interest, and dances with someone else one Saturday night. By the time Pearl Harbor is attacked, Lieutenant Tom Shafer has been home on leave, explained how busy he's been with officer training, and made sure Pam will be waiting for him after the war. He's also had a fight with the guy who won't leave her alone after that one dance. But is it safe to leave her in the same town with this obsessed bully? How can Tom fulfill his promises to protect both his country and the love of his life?
