When Duff Daniels (John T. Woods) steals an ancient snake, the Unteka, from Native American snake proprietor Screaming Hawk (Ben Cardinal), he is given three rules to follow: 'Don't let it out of the jar', 'Don't let it eat anything living', and 'Never fear the heart of the snake'. Unfortunately, Duff soon breaks the rules and it is left to ophidiophobic paramedic Les to right his brother's wrong, with help from his girlfriend Erin (Siri Baruc) and Screaming Hawk.
