Thirty years ago, evil Immortal Quenten Barnes was executed in the electric chair, and promised he'd be back. Escaping the tomb that he has been captive to for the last several decades, Barnes begins hunting down the people involved in his execution. Joe Dawson learns that he has returned and tries to get MacLeod involved in Barnes' apprehension. Mac declines to get involved unless Barnes gets in his way, but when his old friend Michael Moore comes to town, a flashback shows us that Barnes killed Michael's wife and has a long-standing grudge against Michael. Now Mac is involved. He convinces Dawson to share the Watchers' surveillance file on Barnes with him. However, the file isn't much help. As the prosecutor and priest who were at Barnes' execution are killed off one by one, it becomes clear that Barnes will come after Michael next. The story ends with an interesting twist as MacLeod must make a decision that will affect the ""lives"" of two different personalities.

Meanwhile, Gregor appears to have changed since Duncan knew him, as he appears to have become disillusioned and can no longer feel emotion.

Determined to investigate the death of his old friend Darius, MacLeod follows a lead back to his old stomping grounds in the Pacific Northwest. He meets Joe Dawson, a bookstore owner with a secret; he soon learns that Dawson is a high-ranking member of an ancient secret organization known as The Watchers, who observe and record the lives of the Immortals, passing their archives down from generation to generation. Unbeknownst to Dawson, his brother-in-law, James Horton (the man who killed Darius), has been recruiting Watchers to kill Immortals. We are left with the knowledge that other renegade Watchers may be waiting to try for MacLeod's head.
