Virginia Cunningham finds herself in a state insane asylum...and can't remember how she got there. In flashback, her husband Robert relates their courtship, marriage, and her developing symptoms. The asylum staff are not demonized, but fear, ignorance and regimentation keep Virginia in a state of misery, as pipesmoking Dr. Mark Kik struggles through wheels within wheels to find the root of her problem. Then a relapse plunges Virginia back into the harrowing 'Snake Pit'.
