Suzanne Terry's expose on the Chicago heroin trade results in her brutal beating by drug pushers, so the MCU scours the slums to find the culprits despite Chief Kramer's order to keep pursuing Frank Holman. Mike Torrello is so upset by the death of his best friend that he refuses to attend Kehoe's funeral & again comes close to a murderous confrontation with Ray Luca. Phil Bartoli scolds Ray for failing to answer his summons promptly & get permission for the jewelry score, but Luca is unapologetic. David Abrams's rage at Suzanne's assault leads to bloody but unexpected consequences. Mike grows closer to Inger, who remains engaged to another man, while Federal prosecutor Breitel turns up the pressure on Torrello.
