When racketeer Danny Mundt decides the time has come to get rid of Eliot Ness, he hires hit man Elroy Daldran. During World War I, Elroy had developed a taste for killing and he saw no reason to stop doing what he liked just because the war was over. His first attempt to get Ness - he tosses a grenade into his passing car - isn't entirely successful. Ness manages to jump out of the car before the grenade explodes but when he regains consciousness, he finds that he is blind.
