A group of teenagers vacationing in the tropics takes a boat out to a seemingly deserted island. They soon find, however, that the island is inhabited by a wealthy recluse (Graff) and his staff. While their host is initially hospitable, he quickly reveals his true purpose: to hunt down and kill each of his visitors, as he has done with everyone unlucky enough to set foot on his island.For tropes and specifics relating to the Mystery Science Theater 3000 version, please check the episode recap.
This film contains the following tropes:
- Action Girl: Zig-zagged; Betty can flip an attacker effortlessly so long as there's a conveniently uncovered vat of acid for him to land in, but she spends just as much time acting the Damsel in Distress.
- The Alcoholic: Tony, the kids' boat pilot
- Chekhov's Skill: Betty's judo training.
- Gorn: The shot of Balleau impaled through his throat and wrists is quite shockingly graphic, especially for being shown on TV.
- Or it would be if the spikes coming out of Balleau lined up horizontally, as they did before he was impaled.
- Hoist by His Own Petard: Balleau is impaled on the display rack he had purposed for the heroes.
- Hunting the Most Dangerous Game: Well... duh.
- Loners Are Freaks: Balleau.
- Made of Iron: Balleau's henchman survives being abandoned in leech-infested quicksand, and later shrugs off multiple point-blank gunshots when killing Balleau.
- Non-Action Guy: Pete the Nerdy Nerd
- Public Domain Soundtrack: The music for this film has been used in several others as well, perhaps most notable in The Unearthly, another film lampooned in Mystery Science Theater 3000.
- Smug Snake: Balleau.
- Together in Death: Balleau's adultrous wife and her lover end up Stuffed Into the Cave together.
- Wax Museum Morgue
- You Have Failed Me: Happens to both Balleau's primary henchman and to Tony the boat pilot who is paid by Balleau to bring him hunting victims.
