Rattlers1976

Horror Vault's take

When a string of unusually aggressive rattlesnake attacks leaves a trail of bodies across the desert, a herpetologist is called in to find answers — and what he uncovers reaches far beyond simple animal behavior. Teaming up with a photographer, he follows the evidence into dangerous territory where the natural and the man-made collide. This low-budget 1970s creature feature taps into Cold War-era anxieties about military secrecy and the consequences of tampering with the environment.
