The stories of two people become an opportunity for discussion between doctors from Poland and around the world, supporters and opponents of the procedures used today to adjudicate brain death. In 2003, 11-year-old Agnieszka suffered a brain injury after falling from a horse. Despite pressure contrary to procedures and applicable law, her parents did not consent to the declaration of brain death and the commencement of the transplantation procedure. Today, Agnieszka is an independent, adult graduate. On the other hand, Łukasz, who is in his twenties now, is living with his parents and using a wheelchair, lost consciousness at the age of 19 as a result of a car accident and there was no contact with him for many months. Also in this case, the parents did not believe that their son would remain in a vegetative state. Prominent specialists are trying to find out whether the tragic mistakes are the result of medical errors and procedural violations or if the concept of brain death is based on assumptions of a worldview nature that do not have sufficient proof in science.
