The command crew are put in a difficult position when a unit of Psi Cops, led by Bester, comes to the station to arrest the colony of telepaths. The secret of Sheridan and Lochley's past is revealed.

Lyta becomes closer to Byron and the colony of telepaths while Franklin investigates a terrible secret from the Hyach's distant past.

It is the Brakiri Day of the Dead. They purchase a large section of the station for their holiday. That night everyone in that sector meets with people who have passed away. Most of the inhabitants of the sector are happy to see their loved ones, but Lennier's encounter leaves him with troubling news about his future.

Byron and other telepaths seek a homeworld of their own.

Lochley asks Bester for help in dealing with a group of telepaths who have locked themselves in an area of Downbelow. G'Kar is reunited with an old friend in the Centauri royal palace.

A group of telepaths hold Garibaldi and others hostage on Babylon 5.

Garibaldi is sent to retrieve a witness to the shipping line attacks from the Drazi homeworld. G'Kar becomes a figure of veneration among the Narn. Stephen comes to a difficult decision.

A day in the life of Alfred Bester, who starts his day in Psi Corps HQ, where he is well liked and respected. He gets an assignment to track down a rogue telepath. Two recruits accompany him. They follow the telepath's trail to Babylon 5, where he isn't as popular.

Delenn reassigns Lennier to a Ranger training mission on the border of Centauri space. Vir learns he is the new Centauri ambassador to Babylon 5.

Sheridan finally discovers why Delenn had Lennier assigned to the White Star Fleet, and orders his ship to return. But Lennier takes his fighter and continues his mission, where he finally gets the information the Alliance needs. Lyta contacts G'Kar and reminds him of the offer he made to her in "The Gathering." She's willing to help the Narn in exchange for money to find a home world for telepaths.

The Alliance show the member worlds evidence of the Centauri actions, while Londo and Vir are in their room with copies of the evidence. Eventually they're let into the meeting, where they all see the evidence Lennier gathered. Sheridan comes up with a plan to peacefully enforce a blockade, but Garibaldi's issues jeopardize his plans.

Londo and G'Kar return to Centauri Prime to figure out who in the government started the attacks, and are put in jail. G'Kar eventually figures a way for Londo to get out, and Londo tries to gather support. Garibaldi learns of two member worlds's plans to attack Centauri Prime. He informs Sheridan, who rushes off to try and stop the attack. Delenn and Lennier head back to Minbar to convince the council to build new ships, but are attacked in hyperspace. Lyta and Franklin find out what's been controlling the Centauri attack fleet.

On the now devastated Centauri Prime, Londo ascends to the throne after learning to his horror his secret masters who arranged all this.

Back on Babylon 5, G'Kar finds himself the focus of a Narn religious movement while Garibaldi and Lyta have their own personal problems.

Garibaldi and Lise are going to get married. He'll run her late husband's company. An assassin is hired to kill Lise. Zack has a plan to smoke him out, but another person wants G'Kar dead as well. Both attacks are prevented. Garibaldi deals with the people who ordered the hit on Lise. G'Kar and Lyta leave the station.

The various veterans of Babylon 5 prepare to go their separate ways, but not before Lennier makes a terrible but foretold mistake.

Nearing the end of his 20 year life extension, Sheridan bids his farewells to all his friends and family, while the now obsolete Babylon 5 is prepared for decommissioning.
