Nine persons sign up for a self-awareness course at an isolated country estate. Dr. Romero, a charismatic therapist, and his assistants confront the patients with their problems. Cut off from the rest of the world, the participants are increasingly drawn into the therapy's spell. After a week, the unexpected occurs: Romero is murdered. The group breaks out in a panic, and a psychotherapy course turns into a campaign of psychological terror. Grotesque accusations, mix-ups, accidents and false assumptions bring the situation to a climax. Everyone loses control in a growing spiral of hysteria, which ends in an unavoidable catastrophe. But there is one survivor, the shy Gabi, the most inconspicuous of the group and the therapist's murderer. Freed from her phobias and allergies, she disappears into the glow of a red sunset, determined to start a new life. Total Therapy is a tragicomic thriller and a stinging metaphor for a world gone mad in which the self-proclaimed saviors usher in the apocalypse.
