The final episode of The Untouchables revolves around Roy Dahlgren (Jeremy Slate), a crazed WW1 veteran. Elliot Ness (Robert Stack) would like to know why all of the top gangsters in Chicago are leaving town in droves. The reason? The crooks want to establish an alibi when Ness is rubbed out. Mob boss Danny Mundt has offered $10,000 to anyone willing to kill Ness. The deranged Dahlgren accepts the assignment, preparing to finish the Fed off with his weapon of choice--a hand grenade. The climax finds a temporarily blinded Elliot Ness approaching a showdown with Dahlgren, who may or may not have one grenade left. ~ Hal Erickson, Rovi
