The film centered on film crew who become stranded on an island with a crazed crewmember who wants to make his own real life "death movies" or Exploitation films.
Island of blood song
A film crew and a motley collection of thespians set out for an island that will be the perfect location for their next feel good, light hearted, comedy picture. But unfortunately someone has other ideas and destroys their mode of transport before finishing off the surviving cast and crew (wearing a skull-like mask) with the aid of a chainsaw, machete, and nail gun.
The murders are performed according to a sick sado-masochistic type of song, which this homicidal psycho has a fetish for). This psychotic murderer also has an accomplice, a fellow crewman who is skilled in the art of booby traps, rigging a shower to rain battery acid and scalding swimming pool that boils alive anyone who falls in.
