Ted came here with a secret purpose: to find the murderer who killed his wife in the fire. During the investigation, more and more evidence proved Ted's inference: in addition to the 66 mental criminals with files, there was another person with the number 67, but no matter the prison guards, doctors or other patients denied it.
Ted is convinced that this 67 is the murderer of his wife Lydia, and there must be a big conspiracy. But his companion Chuck reminded him that this might be a secret laboratory of the government.
The government sent Ted here because Ted was traumatized by the tragic death of his wife and was their best research object. Ted denied it, saying that he applied to investigate the case here. He suspected that the murderer who caused his wife's tragic death was hiding on this island, and things became confusing.
Ted's migraine symptoms are getting worse and worse in the investigation, and hallucinations and nightmares often appear. When he joined the army, the horrors of Nazi concentration camps kept flashing before his eyes, and he vowed not to let Nazi acts appear here again.
