Ashok and Kumar are best friends. Shanaya and Mishti are their love interests. Ashok's father is a billionaire but has been in a coma for the last six years. During these years, Ashok's maternal uncle, Kunwar Amar Nath Singh (KANS Mama) has been in charge of his family property. Having enjoyed the money, Mamaji does not want to give up that money to Ashok, who is now old enough to take over. So the evil Mamaji teams up with an evil doctor and chemist, Dr. Khan, to get rid of Ashok (without murder) and keep control of his property. Dr. Khan gives Mamaji a medicine called MAD (Mind Altering Drug) which makes one act and speak like a dog for 24 hours. At first, Mamaji is reluctant and angry at Dr. Khan. But Mamaji then sees the medicine work on Dr. Khan’s two assistants (Chinku and Pinku) and agrees. Towards this end, during a board meeting, Mamaji mixes the medicine in Ashok and Kumar's drinks, and they both start behaving like dogs. The men-behaving-like dogs are taken to a
mental asylum for treatment. In the asylum, the lady doctor, Dr. Shivani, soon realizes the truth and promises to discharge them. But fate takes an even stranger twist because, in the same asylum, there are two identical lookalikes of Ashok and Kumar who are being treated in the 'B' ward. The lookalikes worked at an Indian food stall which was a front for Bijlani, a cocaine smuggler. One day Bijlani delivered a jar of cocaine to Ashok and Kumar mistaking that for flour used it for preparing parathas thereby making the customers go crazy. As a punishment, Bijlani gave them both severe electricity shocks thereby both losing their mental balance and were admitted to the asylum. These lookalikes are accidentally released instead of the real Ashok and Kumar. Shanaya and Mishti, who come to pick up their boyfriends from the asylum, take away the duplicates instead, without realizing anything. All of them go to Ashok's mansion. Here, Mamaji understands the whole mix-up and plans to use the duplicate Ashok to become the owner of the whole business empire. By now, the true Ashok and Kumar also come to know of Mamaji's evil plan, but they are still stuck in the asylum. They are offered help by one of the ward boys, Cyrus, who takes them to a secret ward 'C' to meet 'Johnny' who is (by another coincidence or twist of fate) a look-alike of Mamaji. Johnny has a strange, dangerous habit of attacking people who sneeze in front of him. Ashok and Kumar plan revenge against Mamaji with the help of his lookalike, Johnny. However, they get caught by the asylum's sadistic warden, Y.M. Raj (a supposedly funny play on "
Yamraj," the god of death) before they can escape from the asylum. Y. M. Raj prepares to punish them, but he accidentally sneezes in front of them. Enraged, Johnny beats him black and blue, thus helping the three escape. On the day of the board meeting, the true Ashok and Kumar get ready to expose Mamaji, when Dr. Khan triggers the fire alarm. All the three mental patients escape the building. Now desperate, Ashok and Kumar bump into a dance bar owner named Balbir, who (by another coincidence) is a lookalike of Mamaji. Mamaji now does something innovative: he arranges another set of Ashok and Kumar with the help of plastic surgery from Dr. Khan's two assistants (Chinku and Pinku) who assume their identities. He takes the triplicate Ashok and Kumar to the
House of Commons of the United Kingdom, where the fake (triplicate?) Ashok is to hand over all the business to him (Mamaji) in the presence of
Prince Charles. However, the real Ashok and Kumar arrive, along with Balbir (who is Mamaji-III). To add to the confusion, the three mental patients also storm in to help the real Ashok and Kumar, creating panic among the eyewitnesses on seeing so many lookalikes together. The film closes with Ashok's father coming out of his coma and recognizing the true Ashok and getting Mamaji arrested for his deeds. ==Cast==
