There he learns that the youth ward is closed and finds himself stuck in the adult ward. One of the patients, Bobby, soon becomes both Craig's mentor and protégé. Craig is also drawn to another 16-year-old, Noelle. With a minimum five days' stay imposed on him, Craig is sustained by friendships on both the inside and the outside as he learns more about life, love, and the pressures of growing up.
