The Big Mouth

Hapless klutz Gerald Clamson is ocean fishing off the Southern California coast when he accidentally drags a scuba diver onboard his boat. The wounded diver, Gerald's doppelganger, tells him about a cache of stolen jewels secreted at a hotel on the beach. Pursued by two different gangs who both want the diamonds, as well as sexy stewardess Suzie and hotel employee Bambi, Gerald dons a variety of false identities in an attempt to find them for himself.
