S1·E38 To Bury a Friend

A friend from the old neighborhood asks Mike to travel to Chicago to claim the body of her son. While visiting the Windy City, Mike learns that the young man was murdered and the police don't appear to be interested in investigating the crime. When Mike visits the murdered man's room to pick up his personal effects, he is attacked and brutally beaten by a pair of thugs who want to know where "it" is. Mike has no idea, but he's determined to find out and make the two goons who attacked him which they'd never been born.
