Plot

Dr. Hal Raglan, a psychotherapist, encourages patients with mental disturbances to let go of their suppressed emotions through physiological changes to their bodies in a technique he calls "psychoplasmics". One of his patients is Nola Carveth, a severely disturbed woman who is legally embattled with her husband Frank for custody of their five-year-old daughter Candice. When Frank discovers bruises and scratches on Candice following a visit with Nola, he informs Raglan of his intent to stop visitation rights. Wanting to protect his patient, Raglan begins to intensify the sessions with Nola to resolve the issue quickly. During the therapy sessions, he discovers that Nola was physically and verbally abused by her alcoholic mother, Juliana, while neglected by her co-dependent alcoholic father, Barton, who refused to protect Nola out of shame and denial.
