A submarine newly commissioned is damaged in the opening days of WW II. A captain (Cary Grant), looking for a command, insists he can get it to a dockyard and command it. Going slowly to this site, they find a stranded group of Army nurses and must take them aboard. How bad can it get? Trying to get a primer coat on the sub, they have to mix white and red in order to have enough. When forced to flee the dock during an air attack, they find themselves with the world's only Pink submarine, and 5 women yet! Here's a funny scene with Tony Curtis stealing a pig, which he names Seaman Hornsby, and then trying to hide it in the Officer's Head.
