In the second-season opener, the squad is plunged into a case involving the death of an admired police officer who may have been involved with a white supremacist group. The case hits home for Dwight, who relates to the son of the officer left behind. It also introduces Dwight to Claire Ryan (guest star Beau Garrett from TRON: Legacy), a tough investigator from Internal Affairs. Meanwhile, Rice starts riding Whitehead about taking the lieutenant's exam, but her reasons for wanting him to pass aren't exactly a vote of confidence. (thetvdb.com)
