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.

Nick is working for Bert trailing a suspect in an industrial theft case. He witnesses the man being killed by a woman, Marta, who claims diplomatic immunity. While Bert holds the woman in custody through his connections, he needs Nick to recover the plans at the woman's embassy. Nick needs a partner, an experienced thief. Amanda is on the run from an obsessed Immortal, Stefan Collier, and accepts the job as a diversion. Posing as husband and wife, they go into the embassy at a part and try to steal the plans. However, Marta manages to escape from jail and returns to the embassy, interrupting their plans. The two try to get the plans, but are distracted by Collier arriving on the scene. They catch up to Marta at the airport and take the plans. Marta declines efforts by Bert to help her, even though we find out she's his ex-wife.

After a flashback/dream by Bert Myers to his career in Eastern Europe as a spy, cut to modern-day where Bert and his girlfriend Catherine are having problems. Bert needs Amanda to break into the house of Ludwig. He doesn't tell her he needs some files that Ludwig has on him from the past that he can blackmail Bert with. Bert ends up shooting Ludwig in self-defense while an unknowing Amanda steals a painting and later sells it to Basil. Shelater finds out about the murder, and thinks Bert set her up (since the painting she sold can be traced to the house). Bert buys the painting from Basil and gives it to Amanda. However, Ludwig's protege still has the files, and forces Bert to try and kill a Indian ambassador, Chandra, by using his security firm. Bert refuses, and he and Nick manage to intercept the protege as he attempts the assassination. "Chandra" escapes in a limo, but it's actually Amanda. The driver is Bert's girlfriend Catherine, who was planted on him by Ludwig as a contingency.

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

Two of Bert's bodyguards are protecting a flighty actress when one is shot and killed. Nick is called in, and prevents another apparent assassination attempt, only to realize the assassin is a man, Frank Brennan, that he killed four years ago. In flashback we see how Nick and Bert met for the first time, when Nick inadvertently rescued Bert when Brennan, a rogue NSA agent, tried to kill him. Brennan isn't after the actress, but rather the people involved in his first ""death"" which made him immortal, and who are now guarding her. Amanda and Nick manage to thwart Brennan before he can kill Bert, while keeping the secret of Immortals away from Myers. Amanda confronts Brennan, who shoots her. Nick shoots him and Amanda takes his head. Copyright 2002 Steve Crow
