The circus is about to close and only a few patrons are left. An ordinary man, who actually works at the circus, asks woman if they have a sister or girlfriend with them. If they don't he tells them he thought they looked like someone he knew and tells them to forgive the intrusion. If they do he tells them that there has just been two woman killed and for each there was a witness that says a man dressed as a clown was responsible. He also tells them they think they know who it is but the closest and safest place to go is a nearby building he directs them to. He tells them the exit is a risk since it is all the way on the other end of the park. Once they go to the building a clown there holds them captive. Then the man who warned them tells them that they had better call their sister or girlfriend or he will kill both them and from their ID track down their family and kill them. Once the girlfriend and or sister arrive both he and the clown make sex slaves of them and do various other non sexual things to them. This would require the female to take on both roles. The details are negotiable.
