Plot:
In the swamp at night, Lem shoots something large.
Later, at the general store, Liz, the uber-hottie wife, of the store owner, Dave, so fat he may be the hiding place for Al Capone’s treasure. She is completely disgusted by
him. The guys are listening to Lem talking about the thing he shot having giant suckers. Of course, they think he’s out of his gourd so heads out to check his traps.
Liz gets ready to head out and ignores Dave. Give us the gams, Liz…
Back in the swamp, Game Warden Bill Benton tries to catch some poachers. He and his girlfriend, Nan, hear a scream. They find Liz who freaked out when she found
Lem’s corpse.
The sheriff won’t believe that Lem’s death was anything but an accident. Game Warden Bill won’t let it go because it wasn’t a boating accident or an animal attack.
Game Warden Bill checks with Nan’s father, the Doctor. They think that Lem’s creature could exist and the heroic game warden will search for it.
Back at the general store, Liz pitches a fit at Fat Dave. He leaves to make a delivery. While gone, Cal, one of the locals, puts the movies on Liz. I believe something about
how she’d make a nice notch on his bedpost was enough for her to fall head over heels with him.
Game Warden Bill and Nan are getting discouraged in their search.
As Cal and Liz are trying to rut like depraved pigs in the late 1950s, she explains why she married Dave. Well, the unhappy, Fat Dave appears with his shotgun. He forces
them to go into the swamp and keeps catching up to them and forces them deeper into the swamp. Cal and Liz are in the lake when creepy music plays, and the Giant Leech gets
Cal and Liz.
The next day has the locals searching the lake for the bodies. The sheriff who is slightly dumber than dirt is positive that Fat Dave shot them both. Well, Fat Dave is arrested
and taken to jail where he hangs himself.
Game Warden Bill refuses to let doctor use dynamite to destroy the monster. Hero is sure that Fat Dave killed them and hanged himself in remorse. Doctor is sure the creatures
are nocturnal. Hero boy doesn’t believe it.
A couple of rednecks search the lake because they’re sure that some gators got the bodies. As the creepy music plays, they realize they haven’t seen any gators when the
Leeches tip the canoe.
Later, Cal, Liz, and the rednecks are in a cave. The swarm of Leeches feasts.
Game Warden Bill learns that the rednecks disappeared. He’ll search for them.
In another too dark to see scene, the search party ensues. When they’re about to call it a day, they realize there are no gators in the lake.
Game Warden Bill wants to test the water to see what drove the gators away or dive into the lake. The good doctor wants to use explosives since no animals are in the
lake. Game Warden Bill gives his spiel about the conservation of life, etc…
Later, doctor sneaks out to the lake and lets the dynamite fly.
In the cave, Cal and Liz are being drained by the Leeches.
The explosion rocks the cave and knocks some bodies into the lake where they surface, 3 bodies but not Liz’s.
Game Warden Bill is about to head to the coroner’s office and going to arrest the good doctor. The doctor reveals that Cal wasn’t killed by Dave. The bodies were drained
of blood. The area is peppered with caves and some caves under the lake.
Game Warden Bill readies his SCUBA gear and other diver, Steve. The Sheriff and the townsfolk are at the shore watching this.
Ronny James Dio’s Holy Diver fu ensues. Steve discovers the entrance to the cave but signals for help.
Doctor is convinced that atomic radiation is responsible for the Leeches.
Liz falls off the ledge into the lake and surfaces. Her face is scarred.
Steve heads back to the cave and encounters the Leech monster. Game Warden Bill in his SCUBA glory comes to the rescue. Stabbing fu. They surface and head for land.
Nan embraces Game Warden Bill.
Later, the dynamite charge is readied. And Bill sets the charge off. The explosion causes the Leech to surface. Everyone leaves but we hear the Leech creepy music. So is
it over or not?
