Amanda is breaking into an exhibit of artifacts from a an old sailing ship when she is interrupted by two "amateurs" who set off the alarm. One of the men throws himself through a window after being shot, and is dragged out of the water dead. Nick suspects Amanda's involvement, and the police suspect both of them are involved. Amanda was after artifacts she had left on the ship in the past, from when she had helped a family of slaves. The "dead man" (who took a voodoo-type drug to fake death) is the descendent of that family, trying to recover a deed that freed his family and granted them property. He finally expires from his gunshot wound, but Amanda can't recover the deed alone and gets Nick to help her. They duck into a bathtub just in time to keep the police from catching on, leaving Amanda wondering where Nick got that tattoo on his butt...

An Immortal stalks and kills Donald Magnus, the brother of Nick's former captain Carl Magnus. The Immortal is a soldier, John Ray Fielding, and the brother had killed Fielding's men in the Gulf War due to "friendly fire". Fielding killed brother Donald to avenge his fallen comrades. However, in flashback we find out that Fielding "died" for the first time when Amanda stole orders from him that resulted in the death of him and his men. Now Fielding is out to kill Amanda. Unable to live with the guilt of what she has done, of actually killing people due to her irresponsibility, she yields herself to Fielding who kills her and prepares to take her head. However, Nick convinces Fielding that she has "died with honor" and there's nothing further to be won. Saluting Amanda's courage, Fielding departs.

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

Nick is hired to return a painting by Sir Trevor, and invites Amanda along so she can get a taste of "doing good." The picture is mysteriously restolen as they leave, and Amanda's past raises the suspicion of the local police. It turns out that another Immortal, Jade, patterns herself on Amanda and likes to one-up her. The two have been rivals for centuries. Things get further complicated when Jade tries to sell the picture, and Nick and Amanda manage to recover it. It turns out that Trevor had a fake picture stolen for the insurance, and plans to secretly sell the original. The duo's return of the picture screws up his plans, but since the fake is in the gallery they'll be in trouble as well if Trevor reveals he got a fake back. Amanda and Nick strike up an alliance with Jade: she shows them the secret passage into the vault and they return the real one. They then knock out Trevor and make it look like he was trying to switch pictures.

Nick and Amanda work to stop a casino theft, but fail. Amanda realizes the ringleader is Jeremy Dexter, a fellow Immortal and thief that she has teamed up with several times over the millennia. She doesn't want to give Jeremy up to Nick, who has other ideas. Nick is being accompanied by Interpol agent Nicolae Breslaw (from the Highlander episode "The Valkyrie"), who is out for revenge because his younger brother was gambling in a casino with his company's money when Dexter robbed the place, and killed himself afterward. Nick and Amanda eventually set it up so that Breslaw can "kill" Jeremy, but he refuses to. Nick has to do so instead, leaving Breslaw to believe Dexter dead so that the latter can sneak out of town on Amanda's money.

A woman watches her partner get gunned down...and we next see her at the bar. She is Nick's ex-wife Lauren. A lawyer, she is pursuing an organ bootlegging case against a Dr. Julian Heller. Heller is an Immortal, who makes a huge profit on using his medical practices to corrupt purposes. He and Amanda had a run-in centuries ago when Amanda assisted as a midwife for a woman accused as a witch. Amanda escaped then and still holds a grudge, but Nick insists it is personal. He and Lauren briefly rekindle their romance, but Heller then has Lauren killed. Swearing revenge, Nick goes after Heller. Amanda gets there first, but is knocked down a flight of stairs and briefly killed. Nick arrives and drives off Heller before the latter can take Amanda's head. Nick takes Amanda's sword and goes after Heller with his gun. A game of cat & mouse ensues, but Nick gets the upper hand and takes Heller's head. Amanda arrives just in time to get the Quickening, leaving Nick to lament what might have been.

A cyberhacker and his employer kill each other in a shootout...and the employer, an Immortal, walks away. The hacker's sister Janet is a friend of Amanda's and the duo get involved. Nick tracks a back-up CD to the Immortal, whom Amanda recognizes as Payton, an astrologer, poisoner, and stage magician who ran afoul of Amanda centuries earlier. Payton assaults Nick and then escapes with a poisoned-smoke grenade, giving the detective 22 hours to live. He'll give Nick the antidote if they stay out of his affairs. Amanda gets hold of the 10 million Payton was stealing, and Payton kidnaps Janet in return. They arrange to make a deal, and Amanda engages Payton in combat. He tries to trick her using a holographic projector but a dying Nick destroys it, giving Amanda the advantage. She suffers a rather bizarre Quickening as she flashes back over her life, and her encounters with Nick. Going to him, she asks for forgiveness and shoots him dead before the poison kills him. He wakes up immortal.
