Duke plans to attend West Point after graduation, but right now he and his friends are rehearsing for the Fourth of July talent show. A Broadway agent catches their act and makes Duke a dazzling offer. He accepts, only to discover that his girlfriend, the daughter of a Marine, is heart-broken at his change of plans. He tries to console himself with another girl, but that doesn't work, either.
Fast action, clever skits and some of the best loved music ever composed, including: Give My Regards to Broadway, You're a Grand Old Flag, and Yankee Doodle Dandy!
