Imprint is about a white man, played by cult-hero Billy Drago, in 19th Century Japan searching all the countries brothels for his long lost love. He starts talking with a deformed prostitute, who weaves a twisted tale about her history and eventually what happened to girl. For the most part I was kind of bored, for only being 50 minutes long, it started to drag a bit. But the eventual torture sequence is some of the nastiest stuff I've ever seen. I almost had to close my eyes through some of it... and these scenes never bother me. I laughed through the Saw films.
So if you're really into gross-outs, this is the film for you. If not, don't bother.
