Two brothers, both cadets at Annapolis, fall in love with the same girl.

Portsmouth, 1794. Under thundery skies and in lashing rain, 17-year-old midshipman Horatio Hornblower takes the first tentative steps of his naval career, but a feud with a shipmate causes complications.

Hornblower and his comrades come under the command of a revered but mentally unstable captain and are forced to mutiny in order to save their ship, the HMS Renown.

Six friends, all hoping to become aviators, are to graduate the next day from the United States Naval Academy. When the officer of the day becomes sick, Tommy Winslow has to take his place, while the others go out and celebrate.
