Place at the changing world of the late 1960s, Susanna Kaysen's prescribed"short rest" by the psychologist she had met only one time becomes an odd, unknown journey into Alice's Wonderland, where she fights with the thin line between ordinary and mad. Susanna soon realizes just how hard it's to get out once she was committed, and that she eventually must choose between the world of people who belong indoors or the world of reality outside.
