A serviceman and a starlet find love at the star-staffed serviceman's center.

Slim Green, a corporal stationed in the South Pacific, is enamored of actress Joan Leslie. After he is injured in battle, he and his pal, Sergeant Nolan, are sent to Hollywood, California for rest and recreation before they ship out again. When Slim mentions his desire to see movie stars, he is directed to the Hollywood Canteen, a gathering place for soldiers that is run by motion picture actors and actresses. Slim is impressed when he learns that all the entertainment and food is provided free of cost to servicemen and women. Learning that Slim has a crush on Joan Leslie, canteen president Bette Davis and Jane Wyman arrange for the two to meet. The next day, Nolan finds it hard to believe Slim's account of his experience at the canteen. He accompanies his friend to see things for himself and is impressed by the friendliness of the stars. Slim and Nolan continue their sightseeing the following day and accidentally encounter Joan at the Farmer's Market. That night, Slim becomes the millionth serviceman to come to the canteen and is awarded a luxury hotel suite, a car, a visit to a movie studio and a date with his favorite actress. Slim invites Nolan to share his suite and asks Joan to be his date. When Slim takes Joan home, the two sit in the backyard and talk about their lives. The next day, Slim and Nolan visit the Warner Bros. studio and Slim has dinner with Joan and her parents. Before Slim leaves town to return to the war zone, he makes a speech to the servicemen at the canteen, honoring all branches of the service and all the allies for their part in the fight. Joan has promised to take Slim to the train, but on the way to pick him up, she runs out of gas. When she does not arrive on time, Slim writes her a note, thanking her for a wonderful weekend. At the last minute, Joan arrives at the train station, and kisses Slim goodbye.
