Some of these pictures and descriptions may give away plot details that you might not want to know before watching the film.
This is an Italian post-apocalypse sci-fi action flic about a cyborg (Paco - played by Daniel Greene) who is programmed to kill an important scientist but fails because he still has some of the human values he had before 70 percent of his body was bionically reconstructed. When the professor survives Paco's attack, the people who modified Paco hunt him down, so he steals a car and drives to his old home territory in northern Arizona to escape them. He stops at a motel where he meets Linda (Janet Agren) a hot blonde who gives him a job, a place to sleep, and some fun under the covers. Linda runs a motel with a restaurant where rowdy truckers come at night for arm-wrestling contests. Paco defeats one of them which starts a fight. He knocks them all to the floor with his cyborg fighting skills and his hands of steel. Some of the men come back and challenge Paco to wrestle the arm-wrestling champion in the ultimate contest - the loser gets bitten by a rattlesnake.
The day of the contest, the men tie Paco to a truck and drag him around the desert, then tie him up and hang him upside down, hoping to break him so he can't win the contest, but they don't know he's a cyborg, and he shows up ready to rumble.
We see a man carry a large rattlesnake and put it in one of two clear plastic boxes that are placed next to the arm-wrestlers. In the contest, the men have their arm strapped down next to a cage holding a rattlesnake and when the loser's arm is forced down, it releases the rattlesnake which will bite him. Paco wins the match and his opponent grimaces as he sees a rattlesnake crawl out of the opened box onto his hand ready to bite. But Paco uses his hand of steel to karate chop off the snake's head, saving him. Later, his opponent repays the favor by helping Paco and Linda escape.
As usual when snakes are used as weapons, this whole rattlesnake bite punishment is nonsense. The snake might bite the man, but it's more likely it will just crawl out and try to escape.
I'm not sure
what kind of rattlesnakes are used. We see one or two live rattlesnakes in library footage, filmed years and miles away from the actors. They don't look like native US rattlesnakes.They may be some kind of tropical rattlesnake species. We also see one that might be one of the Western Rattlesnake species. We also see some dead snakes. I'm pretty sure the large snake we see carried and put in a box is dead. The rattlesnake that gets head-chopped is also dead. You can even see where they stitched the neck back together before chopping in off.
