I've heard about this movie for years and recently got a DVD from FANGORIA Box Office Spectaculars, which will be releasing it soon. I'd say I DRINK YOUR BLOOD is up there with LAST HOUSE ON THE LEFT and TEXAS CHAINSAW MASSACRE.A group of violent, drugged-out hippies who worship Satan come to a small town. During one of their Satanic rituals they are spied upon by a woman watching them from the woods. This turns out to be the new girlfriend of one of the hippies. Several of the men run after her and rape her.She makes her way back home. Her father, a veterinarian, decides to pay them a visit with his shotgun. They manage to take it away from him and force him to take LSD. He returns home a mess. His grandson decides that he's really going to get revenge.The kid shoots a rabid dog, takes out some of its blood with a syringe and contaminates these beef pies that the hippies buy at the local bakery. All of them eat the food except for the one hippie whose girlfriend was raped.The hippies start going insane from the rabies and start spreading it to the remaining townsfolk and construction workers. Sort of like a zombie movie. The authorities come in and start shooting them all.I found that movie ended rather abruptly but the DVD contains a much better alternate ending that's much more in tune with the rest of the movie.
