A sinister alien known as Deathwalker visits Babylon 5. Deathwalker, the last of the Dilgar, a race destroyed in 2230, claims to have developed a drug that grants immortality to whoever takes it.
When Jha'dur (SARAH DOUGLAS), a sinister alien, arrives in disguise on Babylon 5, she is attacked by Na'Toth (CAITLIN BROWN), atache to the Narn ambassador G'Kar (ANDREAS KATSULAS). As Dr. Stephen Franklin (RICHARD BIGGS) dresses Jha'dur's wounds, Na'Toth is questioned by Commander Jeffrey Sinclair (MICHAEL O'HARE) and Security Chief Michael Garibaldi (JERRY DOYLE).
Na'Toth explains that years ago during the interplanetary wars, her grandfather's family was butchered by Jha'dur, an infamous scientist and was criminal then known as DeathWalker, who was famous for her cruel biological experiments. Na'Toth swore to avenge her ancestor's murders.
Meanwhile, Talia Winters (ANDREA THOMPSON), Babylon 5's resident telepath, is hired by the enigmatic Vorlon ambassador, Kosh Naranek, supposedly to secretly monitor his meetings with a humanoid named Abbut (COSIE COSTA). During the sessions between Kosh and Abbut, Talia senses no emotions or thoughts coming from Abbut. However, she experiences brief memories of a terrifying serial killer whose mind she scanned years earlier.
Talia later learns that Abbut is Vicker, a cybernetic video recorder, who tricked her with his conversations into feeling memories of her most vulnerable emotions, then imprinted her feats on a data crystal for Kosh. Garibaldi and Sinclair suggests that Kosh hired Abbut to discover Talia's greatest fears and plans to use them against her in some future confrontation.
Meanwhile, Sinclair's Earth Alliance superiors order him to Jha'dur to Earth immediately. Scientists are eager to perfect her promising experiments for a youth serum. However, Ambassador Kalika (ROBIN CURTIS), representing the many minority alien races aboard Babylon 5, demands that Jha'dur be tried for her war crimes against their planets by the station's League of Non-Aligned Worlds. To avoid a riot, Sinclair agrees to conduct a hearing.
Evidence confirms that Jha'dur is DeathWalker. Her serum was developed by performing sadistic experiments on the alien minorities for many years. however, for their own political self-interests, a bare majority of the ambassadors, with an abstention from Kosh, vote to send Jha'dur to Earth. Outrages, Kalika and the alien minorities that she represents reject the League's decision. A short time later, fleets of their warships surround Babylon 5.
Sinclair negotiates a compromise with Kalika. A coalition of alien scientists will accompany Jha'dur to Earth and help perfect the serum for the benefit of all races. Afterward, Jha'dur will be officially tried for her crimes. However, Jha'dur tells Sinclair that the active ingredient in her serum is taken from the living tissue of another being. Each donor must die so the recipient can live forever. The scientists who control the serum will become greater butchers than Jha'dur ever was.
As Jha'dur's transport shuttle departs, a massive Vorlon warship appears and destroys it. Having resolved the moral dilemma for everyone, Ambassador Kosh tells the assembled leaders that they are not ready for immortality.
