A band of satanist hippies coil into a town and arise terrorizing the townswoman nation. They rape a county girl and her grandpa goes after them. He fails and is given LSD. This bothers his grandson and he gets back at the hippies about feeding them pith pies infected with blood from a hydrophobic dog. They beat a hasty retreat into crazed lunatics and about killing and/or infecting everything in their scheme.
I saw this as a kid at the theatre in 69 or 70. What a great Grindhouse production! It is in my top 10 list for sure. This movie is also unique in the way the people are infected, def. 1 of a kind, not a copy cat or rip off. If this is your cup of tea, check out my GRINDHOUSE playlist, they are def. my favorites for sure! Watch, enjoy 10/10
