She reminds MacLeod of a vow of protection his "ancestor" (MacLeod himself) made 200 years before. Flashbacks tell the story of MacLeod coming to the aid of the samurai Hideo Koto after MacLeod is shipwrecked in Japan. He vows to Hideo he will always protect the Koto family and is bequeathed the dragon head katana sword he uses to this day. Back in the present, MacLeod discovers that Kent is an Immortal and he's still alive.

Joe Dawson arrives in Paris to let MacLeod know that Horton may still be alive and coming after him. However, when MacLeod meets ""Lisa Milon,"" a dead-ringer for Tessa (Lisa Halle after plastic surgery), all thoughts of Horton and the Watchers go out of his head. Richie, unsure if Mac is thinking clearly, goes to Dawson for help and winds up taking a bullet for him when Horton tries a hit. Lisa is kidnapped, and MacLeod insists on going after her even though his friends warn him it may be a setup. He can't take a chance on burying her again. When Lisa finally tries to kill MacLeod, he turns the tables on her and Horton at long last gets what's coming to him.

Pete Wilder just saved Richie from an attack by some guys wearing Watcher tattoos. Or did he? Nothing is what it seems, and MacLeod becomes increasingly wary of Pete, despite Richie's protests that the guy is his friend. When MacLeod's mistrust gets the possibly innocent Pete killed, Mac becomes increasingly unsure of himself. Unknown to MacLeod, his old enemy Horton is pulling all the strings. Horton is secretly training escaped killer Lisa Halle to go after MacLeod while he's troubled and vulnerable.

Richie returns, on the run, turning to MacLeod for help. An Immortal has been following him, refusing to confront him, but committing grisly murders wherever Richie goes. Richie is arrested for the murders. Mac learns that Immortal hunter Martin Hyde is behind the murders: considering the Quickening of a green Immortal like Richie not worth the taking, Hyde has been hounding him in order to drive him to his teacher. MacLeod must clear Richie of the murders and defeat the evil Immortal.
