Plot:
As the reptiles wander around in the swamp, Tim, our disgruntled protagonist, is doing 1970s enviromental stuff before returning to his cabin. Several members
of the Seminole Indian tribe try to talk Tim into rejoining their tribe after enduring the Vietnam war to no avail.

Rattlesnake isn't exactly a necktie at this point...
Later, Thompkins and his skeevy goon, Crail, stop by Tim's cabin.

My career can't be going down this low...Wasn't I in the GodFather?
They try to talk him into trapping snakes for the blooming animal-skin fashion trend. Thompkins also tries to talk about the death of Tim's father was an accident. Tim doesn't take any of the conversation with sweetness.
Afterwards, Tim stops by a doctor's office where he's been bringing rattlesnakes so their venom to be milked for anti-venom. Stanley hi-jinks nearly ensue when other people don't appreciate the greatness of free range rattlesnakes. Tim stops bya gentlemen's club to deliver a few snakes to Gloria, the dancer. Sydney, her skeevy manager and husband, gets a"brilliant idea for the snakes that willbring in the business after Tim leaves.
The next day, Tim finds a truck full of snakes. He quickly frees them before Crail and Bob return. When they arrive, the fight is on. During, Bob admits that the death of Tim's father was no accident. The goons get out quick fast when Bob gets bitten by a rattler.
Thompkin is relaxing around his pool with some biting repartee with Suzy, his daughter, who wants away from daddy as soon as she turns 18 in a couple of months. The goons report to him about Tim freeing the snakes ad the truth of Tim's dad. They want to hire someone to eliminate Tim and decide on "Psycho".
The club has Gloria with her new act: Cleopatra and her asp. She's not too happy about it.
Back in the swamp, Psycho, Crail, and Bob are grabbing snakes.

I can scream angrily like Captain Kirk's "Khannnnnnnnnn!" yell...
Tim and Stanley engage in swamp warfare which gets Bob and Crail drowning in quicksand.

No Herve Villachez jokes...
Elsewhere, Psycho finds Tim's cabin and smashes Hazel and the baby rattlers to death. Tim walks up and sees Psycho. They fight, and Stanley bites the Billy-Jacked hatted loon. Tim buries the rattlers in a little snake graveyard.
Going into town, Tim stops by the club. He sees Gloria's new act where Cleopatra decides to bite the head off the snake in advance in pre-Ozzy Osbourne style. The crowd apparently loves it but not Tim. Afterwards, Gloria is falling down drunk. Her and Syd stay the night at the club. Tim breaks in and uses his snakes to revenge them.
The next morning, Thompkin's place, Suzy rides off. Tim sneaks in and drops a number of snakes in the pool before Thompkin's morning dip. He gets not a belly flop as much a belly bite.

Maybe an underwater scene would be more impressive than with just rubber snakes...
Suzy returns to see her dad re-enacting the dead man's float. Tim grabs Suzy and takes her back to his swamp cabin.
Tim introduces Suzy to his bestest friend, Stanley. Our noble protagonist also professes his love for Suzy who doesn't quite take any Tim seriously by talking about wanting to head off to a commune. She also chews him out for using the snakes to get his revenge.
Since Suzy refuses to stay with him., Tim starts ordering Stanley to attack her. Stanley doesn't charge at her. Tim gets mad and starts
attacking his snakes for not obeying him.

The kind of movie staredown, movie blockbusters are lacking...
Let the big intimidation begins when Tim tries to out-stare Stanley who bites Tim after Tim apologizes him. The flailing about the room, Tim accidently sets the cabin on fire. Suzy runs out. Tim crawls out and dies. Stanley and the other snakes head off into the swamp to escape the 1970senviro-folk rock end song...
