A U.S. intelligence agent's death is averted when his brain is transferred into the billion dollar "Advanced Design Anatomical Man," or ADAM, a technically perfect and nearly invincible body. Developed by Dr. Eisenberg at the top secret Eden Institute, ADAM is the ultimate 21st century fighting man/machine which, in its "Overkill" mode, transforms from flesh into a fully metallic offensive weapon. When Dr. Eisenberg is suddenly missing with the prototype of his ADAM creation -- a flawed, evil version called ADAMAN -- they are quickly linked to a deadly diamond heist. Soon, U.S. intelligence agent Mark Damon takes over the investigation and finds that David Sanjoni, the husband of former British secret service agent Brenda Weber, has bribed Eisenberg and the super-droid ADAMAN to commit the robbery. On the verge of being caught, Sanjoni sets an elaborate trap that results in Damon's brain being melded into ADAM. Damon must quickly adjust to his new powers to stop ADAMAN in a lethal confrontation.
