Les (Michael Shanks) has been terrified of snakes since he was a kid, when a bite killed his father. Nevertheless, he's intrigued when his snake-wrangling brother (John T. Woods) steals a rare specimen. But the terror begins anew when the reptile escapes. It grows to hundreds of times its original size, slithering through town and leaving carnage in its wake. Now, Les must find the courage to confront the beast before it strikes again.
