　　In 2261, the Vorlons join the Shadow War, but their tactics become a concern for the alliance when the Vorlons begin destroying entire planets which they deem to have been "influenced" by the Shadows. Disturbed by this turn of events, Babylon 5 recruits several other powerful and ancient races (the First Ones) to their cause, against both the Shadows and the Vorlons. Captain John Sheridan returns to the station after escaping from Z'ha'dum, but at a price: barring illness or injury, he has only 20 years left to live. He is accompanied by a mysterious alien named Lorien who claims to be the oldest sentient being in the galaxy.
　　Hours before Sheridan's return, Garibaldi is rescued and returned to the station, in rather dubious circumstances. He is markedly more paranoid and suspicious of other alien races and of Sheridan than he was before.
　　Centauri Emperor Cartagia forges a relationship with the Shadows. Londo Mollari engineers the assassination of Cartagia and repudiates his agreement with the Shadows. Londo kills Mr. Morden and destroys the Shadow vessels based on the Centauri homeworld, in an attempt to save his planet from destruction by the Vorlons. Aided by the other ancient races, and several younger ones, Sheridan lures both the Vorlons and the Shadows into an immense battle, during which the Vorlons and Shadows reveal that they have been left as guardians of the younger races, but due to philosophical differences, ended up using them as pawns in their endless wars throughout the ages. The younger races reject their continued interference, and the Vorlons and Shadows, along with the remaining First Ones, agree to depart the galaxy forever.
　　After the Shadows are defeated Garibaldi leaves his post as security chief and works on his own as a "provider of information". He begins working for one William Edgars, a Mars Tycoon, who is married to Garibaldi's former love. While he works ever closer with Edgars, he becomes increasingly aggressive towards Sheridan and eventually leaves Babylon 5.
　　Minbar is gripped by a brief civil war between the Warrior and Religious castes. Delenn secretly meets with Neroon of the Warrior caste and convinces him that neither side can be allowed to win. She tells him that she will undergo a ritual wherein she will be willing to sacrifice herself, but will stop the ritual before she actually dies. When Neroon sees that she actually intends to go through the entire ritual, he rescues her and sacrifices himself instead, declaring that, although he was born Warrior, in his heart he is Religious.
　　As part of the ongoing conflict between Earth and Babylon 5, Garibaldi eventually betrays Sheridan and arranges his capture in order to gain Edgars' trust and learn his plans. Garibaldi later learns that Edgars created a virus that is dangerous to only telepaths. It is then revealed, that Garibaldi was actually abducted by the Psi-Corps at the end of Season 3 and re-programmed by Bester to provide information to him at the right time. Bester releases Garibaldi of his programming, and allows him to remember everything he has done since being kidnapped. Edgars is killed and his wife disappears, but is reunited with Garibaldi after the end of the war. Garibaldi helps free Sheridan and return him to the campaign to free Earth. An alliance led by Babylon 5 frees Earth from totalitarian rule by President Clark in a short but bloody war. This culminates in Clark's suicide and the restoration of democratic government. Mars is granted full independence, and Sheridan agrees to resign his commission. The League of Non-Aligned Worlds is dissolved and reformed into the Interstellar Alliance, with Sheridan elected as its first President and continuing his command of the Rangers, who are to act as a galactic equivalent of United Nations peacekeepers.
　　In the season finale, the events of 100, 500, 1000, and one million years into the future are shown, depicting Babylon 5's lasting influence throughout history. Amongst the events shown are the political aftermath of the 2261 civil war, a subsequent nuclear war on Earth involving a new totalitarian government in the year AD 2762, the resulting fall of Earth into a pre-industrial society, the loss and restoration of humanity's knowledge of space travel, and the final evolution of mankind into energy beings similar to the Vorlons, after which Earth's sun goes nova.

　　清同治年间，香港已割让了给英国人，广九两地边界相连，但一边讲的是大清律例，一边讲的是大英法律。百姓平民，虽同是中国人，民生风俗，却大有不同。
　　广州陈大喜(喜倌)乃名师爷陈梦吉之内孙，天性聪慧，家学渊源，若肯承庭家训，亦应是个着名状师，无奈大喜生性散漫，逍遥自在，事事不上心，十足奄尖大少，不过，平日仗着祖父的威名，总算受着广州人敬重。加上忠心管家吴三省背后刻苦经营，陈家家声，才勉强维持，其实只是个空壳了。
　　大良戴欢(欢姐)，机灵巴辣，自幼与同乡罗波有婚约，后来罗波出外打工，一别多年，村中姐妹相继嫁人，但戴欢仍默默守候，以至标梅已过。幸好守得云开见月明，波终于鸟倦知还，要迎娶戴欢，戴欢好梦正圆之际，波竟涉入一宗杀人越货的谋杀案中，被捕入狱，大呼冤枉。戴欢救夫心切，闻得广州城最出名的状师便是陈梦吉之孙陈大喜，便到陈家跪门叩头求救。吴三省虽见戴欢可怜，但自知大喜有其表，一定帮不上忙，于是对戴欢诸多留难，迫其知难而退，声言要戴欢拿出三百两才出手相助。戴欢自然没有此巨额金钱，但天无绝人之路，戴欢巧遇同乡姐妹，介绍往铜锣湾打住家工，工钱正抵此数。戴欢一为救夫心切，二不知铜锣湾远在香港，以为只是在广州荔湾边，即不顾一切签字买身。戴欢拿着三百两上门，大喜、三省自然傻了眼，不知如何拒绝之际，大喜竟一手收下，答应为波上公堂打官司！因为这三百两正是大喜急需来香港做大平绅士的水脚！
　　原来陈家有一世交，乃是广州当业世家容德诚，诚年有时曾犯下官司，为梦吉所救，为了报恩，于是指腹为婚，把刚出世的女儿(容蓉)，许配给梦吉之孙大喜。孩登时代，容蓉与大喜时常一起玩耍，容蓉见大喜天性聪明，机智过人相当崇拜大喜，早已决心非嫁入喜不可，但大喜只视蓉为小妹妹，没有将婚事放在心上。时光飞逝，陈家家道中落，相反容家生意却越做越大特别在香港，更成为富甲香江的大亨！然而，容德诚生意虽大，无奈富而不贵，有钱无名，于是设法在香港用钱疏通，欲令未来女婿陈大喜当上太平绅士，便能富贵双全，大大有助于自己在香港的事业。大喜得此机会当然求之不得，唯独欠缺水脚，正巧遇上戴欢，于是冒险接了这场官司，但不懂如何应对，眼见势成骑虎，幸亏忠仆吴三省跟吊随梦吉多年，耳濡目染，暗中指点，加上梦古当年威名，公堂之上，竟把县官吓窒，罗波官司似有转机，戴欢亦庆幸遇此贵人，于是大喜更加牙擦，夸夸其谈，岂料却暴露了其虚有其表，不学无术的弊端，以致官司急转直下，吴三省唯有出手，以陈梦吉的交情求县官轻判，罗波才免除死罪。
　　戴欢看见罗波入罪充军，对大喜可谓恨之入骨，正想找大喜算账之时，竟发现大喜为了避债，早已溜之大吉，乘船至香港当太平绅士。此时买身契亦到期催促，戴欢方知铜锣湾原来远在香港，但已不容后悔，只有与狱中的罗波道别，漂洋到香港做禡姐。正所谓不是冤家不聚头，大喜在香港住大屋做太平绅士，独独吃不惯香港的菜式，为吃地道家乡菜，高薪请了一个大良禡姐，此人正是欢姐！戴欢与仇人见面，不断作弄大喜，后来戴欢在陈家发现陈梦吉遗留下来的案例，得知罗波的案件中疑点重重，要求大喜回广州替波上诉，然而，大喜留恋太平绅士之位，不欲回乡还债捱穷，当然不肯跟从，而且大喜有自知之明，未必能上诉成功，于足百般推辞。戴欢想对策。于是，新仇旧恨一齐来，败家仔遇着巴辣俏禡姐，一段欢喜冤家的关系从此展开。
　　另一方面，大喜在香港亦非自由自在，皆因容蓉时常痴缠大喜，令大喜烦恼不已，更想过离开容家，免再寄人篱下，吴三省则劝大喜忍一时风平浪静，待他朝一日大喜学有所成，则一同回乡重振陈家的名声，大喜只好留下，见步行步。容蓉受人宠惯，生性刁蛮，然而，天生率直，正义感强，一见到不公平的事，则会反对示威，希望改善社会风气，所以很多时候，容蓉都为命令绿衣队长武龙帮手，令武龙左右为难。武龙外表英明神武，但在容蓉面前却言听计从，皆因武龙一直暗恋容蓉，只是不敢向其表白。大喜当上大平绅士之后，当被容蓉缠住，不能脱身之时，便会运用权力，命令武龙收拾残局，武龙本来已不服大喜这个情敌，但又不能违抗太平绅士的命令，唯有照做，但又会惹得容蓉不满，找武龙出气，令武龙对大喜越来越恨之入骨。
