Cary Grant and Tony Curtis ship out for laughs and adventure in one of the most hilarious comedies to ever hit the high seas. Commander Matt Sherman (Grant) has his toughest assignment yet - to put a broken sardine can of a submarine back into action. Enter supply officer Nick Holden (Curtis), a master scavenger with the (illegal) means to get the Sea Tiger purring - or at least afloat. But after the rescue of five stranded (and beautiful) nurses, the grey, battle-scarred sub has suddenly transformed into a pink, party-ready hot tub. Now there's only one course of action Sherman and his men can take - surrender!
