After American scientist gets severely injured and scarred in a car crash in USSR, Russians use metal implants to save him. Once back in the States no one can tell if it's really him so a specialist must determine who is under the "mask".
An enigmatic individual with a metal face is returned from East Germany and claims to be Lucas Martino, an American scientist who was working on a top-secret project but was severely injured and scarred in a car crash. American authorities hold him in custody while they try to establish whether the man is the real Martino or an impostor looking for secret information about the ultimate rocket project developed in the West.
