A group of Satan-worshipping hippies led by a charismatic but menacing leader arrives in a desolate small town, spreading terror and chaos among its residents. Among the townsfolk is young Pete, whose grandfather runs a bakery and whose sister Sylvia becomes a victim of the gang's brutal violence. With the local authorities being ineffectual and no help arriving, Pete devises a desperate plan for revenge. He injects rabid dog blood into meat pies and sells them to the unsuspecting cult members, hoping to turn the tables by infecting them with rabies.

As the tainted meat takes effect, hysteria and violence erupt among the infected hippies, leading to a ghastly transformation marked by aggression and madness. The once terrorizing cult finds itself unraveling from within, amplifying the horror and chaos that envelops the town. While Pete’s plan initially appears to work, it spirals out of control, thrusting the remaining townspeople into a nightmarish struggle for survival. The atmosphere is charged with dread as the infected wreak havoc, blurring the lines between predator and prey and leaving the fate of the town hanging precariously in the balance.
