Five patients suffering from serious mental disorders, after therapy carried out at the mental health department, are entrusted to the care of Carmen who has the task of helping them resume a normal life and reintegrate into the social and working context. All of them go to live in the apartment where they are distrusted by their neighbours, intimidated by their strange habits. Only four of them will be able to regain possession of their lives, overcoming the dark tunnel into which their mind had fallen.
