In the conclusion of a two-part story, renegade Watcher Horton (Peter Hudson) persists in his scheme to destroy both Duncan (Adrian Paul) and Richie (Stan Kirsch). As part of the plan, Horton uses plastic surgery to transform escaped killer Lisa Halle into the living image of Duncan's deceased sweetheart Tessa (Alexandra Van Der Noot). In the course of the intrigue, Charlie puts his life on the line to warn Duncan that Lisa/Tessa is not what she seems to be. Michel Modo makes his last series appearance as Maurice in this, the final episode of Highlander's second season. ~ Hal Erickson, Rovi
