"There is no antidote."
I wish there was an antidote for cheezy straight-to-video disasters like this one.
During the first Iraq war (the one branded by the media as "Desert Storm" in order to sell more crap on TV news shows) the military developed a secret program to infect snakes with an incurable virus called "The Satan Bug." The intent was to create a genetically-engineered breed of super snakes far more agressive and cunning than normal snakes, that were going to be deployed against Saddam's troops. But the snakes were freed when Iraqui terrorists blew up the facility in the Mojave Desert near the town of Santa Mira Springs.
Out in the wild, the super snakes interbred with the local snakes and then they all hung out in a huge underground den for 20 years, because that's what movie snakes do, wait for their cue, then attack. After an earthquake wakes them, snakes start popping right out of the ground, (that's my favorite part, shakes shooting straight out of the ground into the air!) and invade the town. They show up behind bricks and tires and coffee cups, inside toilets, and like lots of movie snakes, they terrorize women when they're bathing.
There's lots more snake nonsense, including evil military brass cover-ups, doctors saying that rattlesnakes are one of the most misunderstood creatures on earth then spreading false information about rattlesnakes, last-minute vaccines, rubber snakes attacking a guy in a helicopter, and exploding snake dens.
They used a lot of fake snakes in the movie and a lot of real snakes, including a variety of rattlesnakes, gopher snakes, kingsnakes, corn snakes, and ratsnakes.
