Pembleton (Andre Braugher) is now a father, but he hasn't got much time to celebrate his baby's birth. Lewis (Clark Johnson) returns from his honeymoon and delivers a startling confession to Kellerman (Reed Diamond). And Giardello's (Yaphet Kotto) career is on the line when the state attorney launches an investigation of a wrongful death. This final episode of Homicide: Life on the Street's fourth season ends on a suspenseful note, as Pembleton suffers a stroke while interrogating a murder suspect. ~ Hal Erickson, Rovi
