"Sinner's Blood" by Neil Douglas is a perfect example of late 60's exploitation trash.The film is loaded with dirt,sleaze and soft-core nudity and features one of the most bizarre and unexpected endings in the history of vintage trash cinema.The action of "Sinner's Blood" takes place in a small American town.Two sisters Penelope and Patricia arrive at their relatives' house when they meet their brother Aubrey.There is also highly unmenacing biker gang which features at least three gay bikers.There are bloody fight scenes,beer drinking,soft-core sleaze and a bit of lesbian sex.The film looks dirty and grainy and there are lots of close-ups.If you enjoyed "Sleazy Rider" or "Wrong Way" give "Sinner's Blood" a look.6 gay bikers out of 10.
