Marco is an introverted and solitary man, tormented and traumatized by his past. He makes a life choice based on science and reason, embarking on a career as a medical researcher and rejecting the education and strange beliefs with which his mother raised him, based on ancient tales, legends and superstitions. Although he has decided to live a life in solitude, the meeting with Maria, a girl suffering from a serious illness, will lead him to question all his certainties and to find an extreme solution, once the science and medical technology to which he has devoted his whole life fail.
