The Untouchables S04E19 - An Eye for an Eye

A father's heartbreak at his son's death leads him to partner with Eliot Ness to bring in a major liquor distributor. Charles Tarasovich knows his son delivered liquor for Sol Girsch and Ness knows it as well, but without a witness who's actually done business with Girsch, there's no chance of getting a conviction. Charles offers to set a trap for Girsch and Ness agrees. Girsch meanwhile has seen his business grow to over 500 distributors and now wants a better deal from those who manufacture the illicit liquor.
