Barker and Ellis are assigned to take down a major drug trafficking ring run by a man named Jimmy Casserly--who happens to be in the Chicago Police Department's (CPD) custody. Barker fears that if Casserly stays in CPD custody, his drug deal won't go... (more) through and they won't have enough evidence to lock him up for good. The partners come up with a risky scheme to bust Casserly out of CPD custody and all is going well until a major wrench is thrown in the gears--an ex cop with a personal vendetta is also chasing Casserly. Meanwhile, Ellis continues to burn the candle at both ends. He runs into Rose and she questions what he does for a living, and Ray from Internal Affairs tries to convince him that Barker is crooked by giving him a DVD with supposed evidence against his mentor.
