Luke Ryland (Benjamin Busch), the demented "Internet killer" first seen on the previous episode "Homicide.com," is freed from prosecution on a technicality -- sending arresting officer Bayliss (Kyle Secor) off the deep end. Meanwhile, Giardello's (Yaphet Kotto) daughter Teresa (Audra McDonald) unexpectedly shows up in Baltimore to help her dad celebrate his promotion to captain -- and her brother Mike's (Giancarlo Esposito) long-overdue resignation from the FBI. Several last-minute revelations, apologies, and surprises occur in this, the 122nd and final episode of Homicide: Life on the Street -- which, in its terminal moments, neatly brings the entire series "full circle." ~ Hal Erickson, Rovi
