Bruno Kirby guest stars as Victor Helms, a former plumber's assistant who was convicted of murder after causing the deaths of an entire family in a gas explosion. Newly released from prison, Helms has sworn vengeance against the Baltimore homicide cop who put him away: Frank Pembleton (Andre Braugher). In concert with his buddy Danny Newton (Richard Newton), Helms conducts a carefully plotted campaign of persecution and harassment against Frank and his family -- a campaign that, unless nipped in the bud, will culminate in murder. This was the final episode of Homicide: Life on the Street's third season. ~ Hal Erickson, Rovi
