Chciago Police Superintendant Nick Bertolucci is a tough top cop. But he has a dangerous enemy on the force: his brother Aldo. Aldo is a beat cop who is eaten up by jealousy and resentment of Nick's success. He gets his chance to sabotage his brother's career when records turn up concerning an illegal raid on a Black Panther household back in 1969. When Aldo tries to connect Nick to the scandal, his scheme threatens to collapse the Chicago Police Department, and his own family, from the inside out.
