Medicore entry with Chan investigating murder of a Federal agent aboard an ocean liner. The mystery aspect is not very well-handled; the ending is especially confusing and unsatisfying. Best and Sen Young's comedy relief is feeble, and the overall effect is 'meh.'

At the end of the film, Number Two Son finds a device that fires the knives used in the murders, yet during the film we clearly see someone throwing them. Again, 'meh.' I do like that we are reminded that Vogan's character is an icthyologist by his reading a book with the title 'FISH,' though.
