Movie about a group of people (i think around 5 or 6?)- all adults I think that wake up(?) in some room (prison cell?) and have to figure out why theyve been brought together even though they seemingly are unconnected & unrelated people. Its possible theres some kind of game where they have to choose who to kill or something because I think they end up killing each other?? I think one of them is an old gay white guy, and something about giving someone else an std? I could be completely making that one up…. but they do eventually figure out why each of them are there/how theyre all connected. I think to a certain extent all of them are shown to have bad characters (I think one person might be unfaithful, another person a criminal, etc.).
I believe the movie is probably from the 2000’s and I highly doubt it was made before the 90’s or after 2015.
