S2·E16 The Last Gauntlet

While transporting a teenaged prisoner, Ness learns how unfair the system can sometimes be when he finds out the truth about the boy's crime.

When gangster Jasper Mullins guns down Al Capone's favorite bag man, the mob boss vows revenge. So Eliot Ness is less than thrilled when he learns that he and Quinlan have been assigned the task of transporting Mullins to trial in Indiana.

Then, at the last minute, Mullins comes down with appendicitis, leaving Ness and Quinlan with transporting a teenaged convict named Cornelius Tucker, who has been sentenced to serve twelve years in federal prison. Of course, Capone's men don't know about the change, so when Frankie Rio joins with hit man Johnnie Peters to kill Mullins, his instructions are to seek out a car driven by Ness.
