The Outer Limits

After flashbacks of an alien abduction drives him to the brink of suicide, Eddie Wexler finds himself at a mental institute, where Dr. Sherrick is using a controversial technique to treat those who believe they have been abducted by extraterrestrials. Eddie and some of the other patients are suspicious of Sherrick and his methods, which forces patients to re-live their abductions in the memory chamber. Some even think that their abductors have infiltrated the institute. Is this just a paranoid delusion or is there an alien face behind the doctor's mask?
