A jolly Police Academy-style navy lark starring Frasier's Kelsey Grammer.

He plays a maverick officer ordered by a vengeful superior (played by Bruce Dern) to skipper a rusty old World War Two submarine - complete with crew of misfits - in a series of war games.

It's an old plot and the humour rarely rises above schoolboy level, but, for all that, this is a good-natured film with Grammer a likeable lead and the now star-billed Rob Schneider a wacky support.
