Jeremy Spensser (Ross Martin), the brilliant young son of a New York family of scientists and humanitarians, is killed in an automobile accident. His death occurs on the eve of his winning the "International Peace Prize," and he leaves behind a wife (Mala Powers) and young son (Charles Herbert).
Jeremy's father, noted brain surgeon William Spensser (Otto Kruger), is distressed that his son's gifts will be denied to Mankind. He conceives a plan to give Jeremy's excellent mind another chance to benefit humanity by transplanting the brain (which he has revived and kept on life support) into an artificial, robotic body. William convinces Jeremy's brother, Henry, an expert in automation, to assist with the process in secret.
Because of its horrific appearance, the huge colossus (Ed Wolff) they've created is kept in seclusion for nearly a year, secretly continuing Jeremy's work on new food sources. However, deprived of normal human contact and possibly of its "soul," Jeremy's mind begins to lose its humanity. He kills his brother, who has fallen in love with Jeremy's wife, and then speaks to his father of the futility of providing food for "the slum people of the world," when it's "simpler and wiser to get rid of them." As Jeremy's mind loses control over his mechanical body, other unexplained powers suddenly emerge from the strictly mechanical body, including mind control of humans and a death ray emanating from both its eyes.
Finally, Jeremy's out-of-control body goes on a rampage in the United Nations building, killing several people. Only when Jeremy's young son confronts the cyborg is Jeremy able to restore his self-control long enough to tell the boy how to switch off and destroy the body of the "colossus."
