Davewas originally a normal businessman, at least he looked very normal. He has a gentle appearance, and a beautiful girlfriend Linda. Unfortunately, during a flight trip, he lost control, was deemed unable to control his emotions, and was sent for "emotion management" training.
The person in charge of this "emotion management" course is Buddy, a psychiatrist who is a bit crazy himself . He created the theory and treatment center of "emotion management". Books on how people control their tempers are selling well. Buddy's therapy is tantamount to a disaster for Dave. The patients in the treatment center were all grotesque, and Buddy kept pushing Dave to do something almost crazy, making Dave feel that even if he wasn't crazy, he was going to be driven crazy. But the worse things have just begun. The court thought that Dave's progress was too slow. If he does not speed up the "treatment", he will be sent to prison.
Driven into desperation, Dave had to endure Buddy's stimulation therapy, such as constantly attacking his girlfriend with foul language, and constantly using Dave's past mental scars to stimulate him. Dave felt that his limit was coming, he hesitated in the two choices he had to retreat and close his heart, or bravely face the complete self. In the end, the running-in adjustment between Doctor Buddy and patient Dave will be a glorious illusion or fall into an endless inner black hole.
