In 1978 Brooklyn as a young Dave Buznik is about to experience his first kiss with the girl of his dreams, local bully Arnie Shankman suddenly pulls down his pants and underwear, exposing Dave's penis humiliating him in front of everybody. Twenty-five years later, Dave works as a secretary for Frank Head, his disrespectful boss who takes credit for his work. Dave's trauma from the bullying causes him to avoid displaying public affection such as kissing his girlfriend Linda in public. His problems are exacerbated by the fact his narcissistic co-worker, Andrew, is still close friends with Linda, who spurns his attempts to rekindle their past relationship. During a flight to a business meeting, annoyed by a flight attendant and a sky marshal Dave loses his temper, prompting the marshal to taser him. He is arrested for assaulting the flight attendant and is sentenced to anger management therapy under Dr. Buddy Rydell, a renowned therapist who sat next to him on the plane. Dave's single session is extended to 30 days, however, after he accidentally breaks a waitress' nose while defending himself from a blind man who kept hitting Dave with his cane. Buddy elects to move in with Dave and join him at work as part of his "radical round-the-clock therapy". This entails unorthodox techniques causing Dave to be passive aggressive. At Dave's workplace, Buddy learns Andrew has a long penis and is shocked to learn of his friendship with Linda. Buddy warns Dave that he should confront Andrew before he and Linda get back together; Dave insists he is "doing okay myself". Buddy sees a photo of Linda on Dave's desk and becomes instantly smitten by her, annoying Dave. To enhance Dave's assertiveness, Buddy arranges for him to visit Arnie Shankman, who has reformed and become a Buddhist monk, telling Dave to exact revenge on him. Arnie expresses his sincerest apologies to Dave for bullying him, but he laughs when Dave reminds him of the kiss incident. Buddy and an initially hesitant Dave provoke Arnie by lying about Dave molesting Arnie's mentally ill sister. A fight ensues between them. After defeating Arnie, Dave and Buddy successfully flee from monks that chased them. Dave is delighted to have had his revenge. Back home, Linda tells Dave she agreed to follow Buddy's advice that they have a trial separation; Buddy explains to an angry Dave this is to give him time to improve his behavior. Dave attacks Buddy when he learns he and Linda have begun dating. Dave is then called back into court where Buddy is issued a restraining order against him. Dave finally snaps at work when he learns Frank intentionally passed him up and promoted Andrew to a higher position. He punches Andrew in the face for meddling in his relationship with Linda and, using Buddy's advice, proceeds to humiliate Frank. He wrecks his office with a golf club and reminds Frank of all his years of loyal service only to be denied the promotion he wanted. He tells Frank that when he gets out of jail, he expects him to do the right thing and give him the promotion Andrew presumably resigned from. Frank agrees and Dave deliberately steps on Andrew's head as he leaves the room. Learning from Andrew that Buddy has taken Linda to a New York Yankees game, Dave assumes Buddy intends to steal his proposal idea and races to the stadium. Security captures him and begins to remove him from the stadium but Mayor Rudy Giuliani orders them to allow Dave to speak. Linda is moved when Dave admits publicly that he has an anger problem and is willing to change. Dave kisses her in front of the stadium crowd before she accepts his marriage proposal. Linda reveals to him that the game was the final phase of his therapy. She explains that the tormentors and the aggravation he has been put through were Buddy's doing: the people involved, including the flight attendant and the judge, are Buddy's friends.
