The director has tried to make the movie Krazzy 4 a comedy flick but most of the times the comedy just don’t work. The movie is a typical Hindi film produced these days. Dr Sonali ( Juhi Chawla ) knows what is best for her patients and knows that to treat her patients she need to also shower love upon them. Raja ( Arshad Warsi ) is the one of the patients suffering from extreme anger and this is why no body wants to even talk to him. Dr Mukherjee ( Irrfan Khan ) who acts as the captain of the team is crazy for cleanliness. Gangadhar ( Rajpal Yadav ) is still fighting for the Independence of the nation. Dabboo ( Suresh Menon ) is a guy who refuses to speak but no one knows why.

One day Dr Sonali wished to take the four patients out for a live cricket match, as a part of her therapy. She stopped the car at her office where she was supposed to take some papers with her. But to the surprise she got kidnapped from there and the four patients were let loose on the road. The reason for her kidnap was her husband R K Sanyal ( Rajat Kapur ) who took this step in search of power and money. Shikha ( Dia Mirza ) working for a news channel joins the patients to help them search Sonali.
