Nick is working with Burt Meyers on security, guarding the head of a telecommunications empire. A sniper takes a shot at the woman, then falls to his apparent death after being confronted by Nick. When the body disappears, Nick suspects Immortal involvement. Amanda is cagey when he questions her, because she knows the Immortal involved: Morgan Kenworth, an old friend whose adopted son was killed by a man named Grady back in the 1890s. Not only did Morgan kill Grady, but he's been killing the man's descendants, ""the best and brightest of each generation,"" ever since. And of course, Nick's client is next on his list. Amanda tries to keep Morgan and Nick from meeting, but eventually Nick tracks Morgan to his silver shop, where he manages to shoot a pane of glass which falls and severs Morgan's head.

Lucy kills an actor with a gun, then tries to cut off his head. The police intercept her before she can succeed and the actor, Wilson Geary, disappears. In flashback we find out that Lucy's husband Marco was an Immortal, and Wilson supposedly used her to set up a trap for Marco and take his head. Wilson has another story, that Lucy seduced him and he only killed in self-defense. Amanda eventually figures out that the truth lies somewhere in-between: a jealous Lucy didn't intend for things to go that far with Wilson, but that he still used her to set up Marco. Now Lucy wants revenge, but upon confessing the truth decides to leave. Geary will have none of it, and kidnaps her. Amanda goes to his theater to rescue Lucy, and takes his head.

A hundred years ago, Amanda was coerced into training with Andre Korda, a ruthless Immortal who raided villages in China. She fled him, but now he's back as a modern-day criminal. The Watchers are on his trail, particularly Joe Dawson (from Highlander). Nick runs into them and is introduced. Korda robs an armored car using his immortality, and Nick insists on bringing him in. Korda escapes when Joe intervenes, since he's taken a vow to keep the Immortals' existence secret. Realizing that Nick won't let it go, Amanda goes to fight Korda's assistant Crysta and takes her head. However, she then disappears and Joe tells Nick that she died. Seeking revenge, Nick travels to Paris and another of Korda's holdings, only to be pre-emptively shot. Before Korda's henchman can finish him, he himself is killed by another shadowy figure who takes Nick away, while Amanda decides to go off to Paris after Nick.

Burt gets the wounded Nick to a Chinese doctor, while Amanda tries to find a gunshot doctor through her connection, the Immortal Father Liam. They both end up together, after the doctor briefly tells Amanda that Nick died. Each is grateful to find out the other is still alive. They then go after Korda, who is stealing various components and kidnapping an expert forger to set up a counterfeiting operation. Nick and Amanda track him into the tunnels beneath Paris, but Korda manages to escape. Using World War II Resistance maps that Father Liam has left over, they track Korda to his main lair. While he's not there, they disrupt his operation. In return, Korda tortures the doctor for Nick's location, and takes Burt hostage. Nick goes to rescue Burt while Amanda faces her teacher Korda in a final battle. She wins. Burt and Amanda buy up Korda's Paris bar while Nick decides to stay in Paris to run Burt's European organization. Copyright 2002 Steve Crow

An explosion at a chemical plant involves Immortal Talia, and Nick gets hired by Garrett, the owner of the factory. Garrett claims that a prototype plastics formula was stolen. Amanda investigates Talia, an acquaintance, and is told that Garrett, Talia's lover, had a sample of her blood and plans to chemically duplicate immortality. It turns out that Talia, a former revolutionary (and who saved Amanda's life during the French Revolution) is now simply in it for the money, and stole a viral plague from Garrett. She plans to sell it to terrorists. While Nick defuses a bomb Talia has planted as a distraction, Amanda fights Talia. She spares Talia's life because she owes her one, but when Talia comes after her anyway, Amanda takes her head. The resulting Quickening destroys the virus for good. Copyright 2002 Steve Crow
