In the conclusion of Homicide: Life on the Street's two-part season five opener, a tense hostage crisis at a Baltimore middle school enters the second day. It soon develops that the deranged man who is holding several teachers and students at gunpoint is connected to an earlier murder in which a pet pig was the only witness. Meanwhile, Munch (Richard Belzer) refuses to make things easy for Pembleton (Andre Braugher), who continues having trouble recovering from his stroke, both at work and at home. ~ Hal Erickson, Rovi
