 At an isolated military installation in Greenland, Major Brothers (Harry Guardino) has allowed one of his men to die after falling in a crevasse. Suffering from hallucinations, he goes to Dr. Hamilton (James Merrill). Hamilton has invented a device that allows him to read the thoughts of another person. Hamilton and Brothers connect via the device, but then a power surge causes the unthinkable: the minds of the two men switch bodies. The deranged Maj. Brothers is bent on destroying the whole base. Unfortunately, his mind is in the psychiatrist s body, and the other base workers know nothing of the mind switch.
