A group of patients meet at a prestigious psychologist's office. Apart from the day and time of the appointment, something else unites them all: all six suffer from OCD. But the plane bringing the doctor is unexpectedly delayed, which forces them to spend an endless wait until the doctor shows up. Will they be able to keep their manias, impulses, convulsions, obsessions and rituals at bay during the wait?
Unfortunately the movie Toc Toc is not yet available on HBO Max.
