Hi, another identify-the-movie question.
This one is probably an american movie. I recall some of the actors had familiar faces so it can't be very esoteric.
The movie is about some kind of strange support group. I think they're all in a house somewhere in the woods but am unsure.
More important: one of the characters is a young woman in a wheelchair (handicapped). There is one scene where she drags herself down stairs without the chair, and tries to make a phone call in secrecy but gets caught. - I think she gets caught by the support group host maybe.
In another scene it is a talk session and one of the women says she used to be a BDSM queen or pornstar and she accidentally killed someone during sex, maybe a boyfriend or a costumor.
Also I think one of the other characters is a man who one of the other women says to mockingly that he cried after they had sex the other night.
I don't remember any more of this... strange movie, need to watch again.
Thanks to all!
