Officer Adam Ruzek works undercover for the Chicago Police Department Intelligence Unit. He is partners with Detective Alvin Olinsky.
Adam's parents divorced when he was a child. The senior Ruzek had served with both Voight and Olinsky. This is most likely the reason that Adam had sought to become a police officer. When Intelligence needed an undercover officer, Adam was taken out of the Academy. Since then, he has remained a member of Intelligence.
While Adam is very eager to please, he sometimes makes impulsive decisions (such as accepting a call from his fiance during a stakeout). This creates friction between himself and his partner, Detective Alvin Olinsky.
Outside of work, Adam is engaged to a woman named Wendy. He does not reveal to her too much about what goes on at work to protect her. They are shown to have a close and playful relationship, sending racy photos of each other back and forth.
Adam and Officer Kim Burgess have a close working friendship, frequently spending time bantering at work. He even helps Burgess get revenge on Platt, a Desk Sergeant who treats Burgess and Atwater horribly. After a particularily stressful call, Adam and Kim share a kiss. Kim regrets this almost instantly as Adam is engaged.
During the a shootout with Jacob Sims, Adam is shot in the chest. The injury is not severe as his Kevlar vest deflected most of the shot.
