As Carol is awaiting trial in the grounds of a maximum security sanitorium, she sees one of the hippies break in and chase her through the grounds. Carol flees into the building and in trying to hide she enters a room containing a hideous experiment: four live dogs, clamped in an upright position, whimper helplessly, their abdomens sliced open and pinned with surgical clamps exposing their glistening innards and still beating hearts. Carol faints in horror. When she comes around, there is no trace of the threatening man. The sanitorium director thinks that Carol's ramblings about the intruder, and the disemboweled dogs, must have been another one of her elaborate hallucinations.
