The murder of gay-basher Ken Reegan on Davies street prompts the squad to re-open the three-year-old murder of another gay-basher, Terrance 'Tron' McLean. Nicco and Len connect with homicide to investigate the case, and Len can't keep his personal prejudices out of the case, which involve working with a gay officer, Luke Darling. Mickey uses the department's new computer toy to help Ali with a 10-year-old arson case. It eventually leads Ali to Boris Delgado, a former troublemaker who found religion after the first fire but was unable to escape his past. (thetvdb.com)
