Per l'immortale Karros la guerra è l'unica ragione di vita. MacLeod ha spesso combattuto al fianco di Karros pur non condividendo i suoi ideali. Ora l'immortale viene chiamato in un paese balcanico per liberare il popolo oppresso, ma il suo fanatismo lo porta ad usare metodi poco ortodossi che fanno inorridire MacLeod.

Friends become enemies and the past is revealed when Immortal Andrew Cord in gunned down and MacLeod discovers the sniper is Charlie DeSalvo, his good friend who used to run the dojo. Charlie, who left MacLeod to fight the good fight in the Balkans with his love, Maria, is after Cord, who murdered her. Dawson knows Cord as the man who saved his life in Vietnam after a mine explosion took his legs and he begs MacLeod not to fight him. MacLeod agrees -- until Cord turns the tables and sets his sights on Charlie.
