Three patients in a mental institution prepare for an examination given by the head psychiatrist. If the patients pass the exam, they will be free to leave the hospital. However, if they fail, the institution will detain them for five years.
The doctor takes the three patients to the top of a diving board looking over an empty swimming pool, and asks the first patient to jump.
