Based on a case history in psychologist Dr. Robert Linder's book "The 50-Minute Hour." Unbeknownst to his friends and colleagues, the outwardly sane and secure atomic physicist Dr. Kirk Allen has for many years been embarking upon imaginary visits to another planet. At first this mental abnormality harms no one, but when Allen begins acting strangely on the job, the Pentagon begins to suspect that he is a security risk. Under psychological counseling, Allen reveals his "secret life" and provides surprisingly accurate extraterrestrial charts as "proof" that he is truly out of this world.
