Raw Force (Kung Fu Cannibals)

When the Burbank Karate Club embarks upon a relaxing cruise, the last thing they expect to encounter is hippie smugglers, white slavery, and man-eating monks looking to raise Karate masters up from the grave, but they do in this lively and decidedly off-beat and campy Hong Kong martial arts adventure. Much of the film is comprised of footage from Roger Corman's 1978 horror film Piranha.
