The Untouchables S04E30 - A Taste for Pineapple

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.
