In the documentary, a very promising way of treating some mental illnesses is presented, which is based on psychotherapy and the use of psychedelic substances, more precisely psychedelic-assisted psychotherapy. In a few years, this form of therapy will probably be firmly established among established medical procedures and is already covered by some health insurance companies. The documentary was filmed in cooperation with the only clinic in the Czech Republic "Psyon - Psychedelic Clinic". Here, they legally use the substance ketamine for psychedelic-assisted psychotherapy. Speaking psychotherapists, psychologists and doctors also mention other psychedelic substances that are officially used so far only in experimental studies. In resistant depression, where all conventional treatment fails, this form of therapy is proving to be an absolute breakthrough. The film also includes statements from clients who underwent ketamine-assisted psychotherapy. They talk about their psychedelic session experiences and what the treatment has brought them.
