this be a very boring 50 b zombie movie about an ex nazi scientist and secretly in america and experiment with atomic energy on human . use recently decease cadaver steal from the morgue and he use radioactivity to bring them back to life and control their movement in order to seek out revenge on enemy . the police and eventually the government be on the case and pick up trace of radio active chemical leave behind by the zombified killer . creature with the atom brain be basically nothing new and be very dull and ridiculous throughout . the zombie get the stitch across the forehead and which be very b movie like and dumb look . laughable and but otherwise do not bother .
