The story takes place in 1954. Federal Marshal Ted Danieland his new partner Chucksent by his superiorsordered to investigate the matter on the island. Doctor Cowley received them and assisted in the investigation. And Ted came here for another secret purpose: to find the murderer Lydis who killed his wife in the flames. During the investigation, more and more evidences proved Ted’s inference: in addition to the 66 mentally ill criminals with files, there is also a person number 67, but no matter the prison guards, doctors or other patients, they are all vocal about this. deny.
Ted is convinced that this number 67 is Lydis, the murderer of his wife, and there must be a big conspiracy here. However, his companion Chuck reminded him that this may be a secret government laboratory, and the government sent Ted to come because Ted was the best test subject after his wife’s tragic death. Ted denied it. He said that he applied for the investigation of this case himself. He suspected that the murderer who caused his wife's tragic death was hidden on this island, and things became confusing. During the investigation, Ted’s symptoms of migraine headaches became more and more serious, and he often had hallucinations and nightmares. The horrors of Nazi concentration camps when he joined the army kept flashing before his eyes, and he vowed not to let Nazi actions appear here again.
In a hidden cave on the cliff, Ted found the missing female prisoner Rachel. Rachel told him that she was originally a psychiatrist here, and the government was conducting brutal and inhumane living experiments here. She could not accept the facts. She designed to frame her and was detained as a "mental patient" before she designed to escape. Rachel told Ted that if he wanted to solve this secret, he had to go to the lighthouse, because there was the root of all this. Ted endured headaches and hallucinations, and dived to the lighthouse, only to find that there was only one guard. He stunned the guard and grabbed the gun and rushed to the top floor, only to find that Cowley, the doctor in charge on the island, had been waiting for his arrival, and the lighthouse There is no trace or evidence of human testing, only a rudimentary office. Cowley told Ted the reason for everything, and his partner Chuck explained that he was actually Ted's chief therapist Sheehan for two years, which shocked Ted like a bolt from the blue.
It turns out that all these are Ted's dreams. The mysterious patient 67, Lattice whom Ted has always suspected, is himself. The doctor told Ted that his real name was Andrew Lattice. His wife suffered from mental illness and committed suicide after drowning his three children. He was also greatly traumatized. The three children completely forgot, and created a brand-new Lattice and the memorable fire. This created “Lattice” was designed by him to be scarred, Persian cat eyes, and heinous. Murderer; he himself is a model husband "Ted" who is a retired police officer and his wife is affectionate. Only when he dreams and hallucinations are his original memories.
All these actions are a drama created by Dr. Cowley to heal Ted’s illness and to cooperate with his consciousness. I hope he can free himself from it. Dr. Cowley is convinced that this method can cure most mental patients. Ted (wanted to fight back against Dr. Cowley's "framing", but found that he was gettingand more confused. Dr. Cowley told him that if he still doesn't wake up and still considers himself a good person "Ted", then he will have to take "moral measures" to remove the white matter of the front lobes. Since he came to this island, he almost hurt all the guards, doctors and patients, but he knew nothing about it.
