Thomas wakes up in a bare hospital room with a tube in his mouth, breathing is difficult. What happened? How did he end up here? He learns that he has been in a coma for three years. He is now 19 years old and the only survivor of a massacre of his family. His mother, father and cousin were murdered, Thomas himself was found with a knife in his stomach and survived. And his sister Laura? She has disappeared. Thomas no longer understands the world, he has no memories of that night. The psychologist Anna is supposed to help him regain access to his memory and thus also be able to reproduce details of the attack. Thomas, who is physically very weakened, remembers little by little. Family life seems to have been anything but harmonious. The mother had an affair, the relationship between the children and her was cool and distant. Then a darkly dressed man appears in Thomas' memories, stalking and terrorizing the family. Thomas is afraid that something could happen to him in the hospital too. He does not feel safe. Anna reassures him that these are visions and pranks of his subconscious. Time is pressing. She needs to know what really happened that night in the family home and penetrates further into Thomas' maze of thoughts. The more the 19-year-old remembers, the more an overall picture emerges for the psychologist. But are Thomas' memories reliable or is he creating his own truth of what happened in order not to have to face reality?
