Jackie Chan's trademark blend of slapstick comedy and martial arts action gets another airing in this adventure based on a Japanese manga series. Womanising crime-fighter Ryô Seaba (Chan) is assigned to track down a Japanese heiress and his investigations lead him to a sea-bound ocean liner. However, once on-board, our intrepid hero finds he has more to contend with than a simple kidnapping case - the liner is about to be hijacked by terrorists and he is the only man who can foil their dastardly plot.
