A man goes to clinic for a routine check-up which takes place at the 7th floor. The doctor finds a reason for a more detailed examination and the man has to stay for the night. The next day more examines are needed and the man has to stay another night. This continues for several days and then treatment is needed which will be performed at the 6th floor. Every new day another treatment is needed until a more specialized treatment is neccesary which can only be performed at the 5th floor. The events keep repeating and the patient moves down the floors of the clinic until he reaches the 1st floor which is meant for terminal patients. Finaly his last descent brings him to the morgue of the clinic.
