Psychological film

hi. i’m looking for a film i watched once. it’s kind of psychological one. it’s about 5 (probably) strangers who went to the psychologist. the problem was that due to the program’s mistake they were scheduled to see him at the same time. so they decided to talk to each other, they talked about their problems and solved them. at the end, it turned out that one of them was the psychologist. it was a method of collective psychology. thanks

see you in september?
