Legend of Oolong Madman

An amateur driver transported three mental patients to a hospital. Unexpectedly, the driver suffered from stomachache and ran to the toilet. The three patients escaped while the driver was using the toilet. The driver was afraid of losing his job and did not dare to report it. When the driver was at his wits end, boss Wu, a financial swindler who drank too much, took the profit-seeking Secretary Liu and the lawyer Li who was exploiting legal loopholes. He mistakenly thought that the car from the mental hospital was a car that came to take them to the bathing center. They acted like a drunk and forced themselves into the car. The driver used a trick to drag the three of them to a new mental hospital. When the three of them were mistaken for patients in the mental hospital and were helpless, they met the creditor who had been deceived by him and had no choice but to hide in the mental hospital. Several people struggled in the mental hospital while looking for a way to be discharged from the hospital. A series of absurd, funny and thought-provoking stories happened with doctors and various strange patients. Their hearts and personalities began to slowly change.
