Woman takes a job at a rural hotel where the proprietor imprisons and tortures her to make her a wife for her slow son.

Actually, for a captivity flick, this is not terrible, a little more unpretentious and character-driven than more, more like it was done in the '70s than modern. Which makes it relatively good, within a really bad genre. Actually goes over the top enough in the third act that it could have been a minor classic in the genre, if it had come out in 1975, and, hadn't taken two slow acts to get there.
