Hunter (Fred Dryer) investigates when a gun manufacturer who is linked to an Irish terrorist organization is murdered. At the same time, Hunter's boss Devane (Charles Hallahan) prepares to pop the question to his sweetheart Maureen Delaney (Fionnula Flannagan). Inasmuch as Maureen's brother Sean (Nicholas Guest) is a noted Northern Irish politician and peace activist, and as such has been targetted for assassination, it is inevitable that the episode's two plot strands will merge in a deadly entanglement. ~ Hal Erickson, Rovi
