Az időszámításunk szerinti 2257. évben egy hatalmas űrállomás, a Babylon 5 (Melyet a Földi Szövetség működtet) kering a galaxis egy semleges szegletében az Epsilon 3 bolygó közelében. A földiekkel és idegenekkel benépesített Babylon 5 politikailag semleges gazdasági és társadalmi központja a négy idegen fajnak (narn, kentauri, vorlon és minbari) és részben a Földi Szövetségnek, akik a galaxis nagyhatalmai és a Babylon 5 Tanácsát alkotják. A Babylon 5 semleges központként üzemel, ahol a különböző bolygók lakói megoldhatják egymás közötti konfliktusaikat.

Az emberek kapzsiságának és terjeszkedési vágyának semmi sem szab gátat. A kentaurik, Londo vezetésével csapdát állítanak a narnok közvetítésével létrejött minbarik és emberek közötti találkozón. Mivel mindkét fél azt hiszi, hogy a másik árulta el, kitör a háború. A Szürkék Tanácsa, Delenn-nel az élén, bosszút esküszik, amikor vezetőjüket megölik. A Babylon 5 űrállomás a bolygóközi békét hivatott szolgálni, létrehozása után Sheridant teszik meg vezetőjévé.

Az árnyak háborúja után a Delta felderítő osztag egy hatalmas tárgyat fedez fel az űrben. A Babylon 5-re vontatják, ahol a hírre azonnal megjelenik egy kutatócsoport, hogy tanulmányozza. Lyta, a telepata, akit a vorlonok különleges képességekkel ruháztak fel, óva int a tárgy feltárásától. A kutatás vezetője szerint a kentaurik ugrókapujához hasonlóan a tárgy lerövidítheti a bolygóközi utazást. Ám a tárgy önálló életre kel, veszélybe sodorva az egész állomást.

Az egyik bolygón végzett régészeti ásatások során egy kutató fura gömböt talál. Titokban magával viszi a Babylon 5-re, ahol Garibaldival kell találkoznia. Lochley kapitány már előre retteg, mert valahányszor megjelenik az állomáson az egykori biztonsági főnök, mindig valami nem várt esemény következik be. Ezúttal is így történik. Az ellopott gömbben milliónyi meghalt ember lelkét tárolják. A gömb megsérül, a lelkek kiszabadulnak. Csakhamar megérkeznek a lélekvadászok hajói is.

John Sheridan (Bruce Boxleitner) rejtélyes látomásban részesül, amit régi ismerőse, a hatalmas technomágus, Galen (Peter Woodward) küld neki. Az álmokat azonban nem csak Sheridan látta, hanem egy kihaltnak hitt faj utolsó képviselője, Dureena (Carrie Dobro), Leonard (Tony Todd), egy földi cirkáló kapitánya és egy drazi is. A négy különböző személyiség együtt indul útnak, hogy felvegye a küzdelmet a drakhokkal, akik a Földet fenyegetik.

David Martel a szigorú szabályok szerint működő Őrszemek rend egyik legjobb űrhajójának kapitánya. Amikor egy bevetésen minden lehetőségtől megfosztottan, legénysége érdekében a visszavonulás mellett dönt, felettesei szigorú büntetés kiszabását helyezik kilátásba. Egy pártfogójának köszönhetően azonban megússza a súlyos büntetést és megbízzák egy látszólag egyszerű feladat teljesítésével. A Szövetség követeit szállító űrhajót kell elkísérnie öreg és baljós múltú új hajójának fedélzetén, változatos összetételű legénység segítségével. A rutinfeladatnak induló küldetés egy ismeretlen faj agresszív fellépésének köszönhetően élet-halál harccá válik.

Sheridan a Tuzenor nevű cirkálón a Babylon 5 űrállomás felé tart, hogy részt vegyen a Csillagközi Szövetség alapításának tizedik évfordulója alkalmából rendezett ünnepségen. A centauri felségterület határán váratlan vendéget kap, felveszi a hajóra Dius Vintari régensherceget, valamint különös figyelmeztetés érkezik a technomágus Galentől. Eközben a Babylon 5-ön Lochley ezredes fogadja a Földről érkezett Cassidy atyát. A pap segítségét kéri egy olyan probléma megoldásában, aminek természetfeletti vetülete is lehet. Lochley szerint ugyanis az űrállomáson lévő egyik embert, Simon Burke-öt megszállta egy démon.

En route to Babylon 5 for the anniversary celebration, Sheridan begrudgingly gives an interview to ISN. He mentions his regret that Londo will not be at the celebration to represent the Centauri, but that his ship will be picking up Prince Regent Vintari, third in line to the throne. The night before the rendezvous, Galen appears to Sheridan in a dream, and shows him a vision of the destruction of New York City. In 30 years, he says, Emperor Vintari will attempt to restore the Republic’s former glory by destroying an old adversary – Earth. This can all be prevented if Sheridan will simply kill Vintari now. But when Sheridan meets the young man, who already feels trapped by the political intrigues of the Republic, he begins to doubt that he can kill a man for actions he has not yet committed.

Douglas Netter, John Copeland, and J. Michael Straczynski talk about the wonderful music Christopher Franke created for the show. Using computers and a full orchestra, Franke created nearly 25 minutes of new music for every episode in the series.

This feature sums up the entire Fourth season.
