　　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.

　　物欲横流的时代，人们该如何面对曾经弥足珍贵的亲情、友情与爱情……

　　民国初年，临江县城…
　　这一晚，大会堂坐无虚席，工商大老和地方仕绅全聚集在此，参加“筑堤修坝募款义演晚会”。主办人是大发面粉厂的老板于伯涛，义务演出的是京剧小有名气的青衣“筱菊花”，和她所属的“大江南剧团”。
　　演出获得空前的成功和回响，也募集到筑堤修坝的费用。县长代表全体县民致谢词，并宣布今晚的演出是筱菊花告别菊坛之作，从此一心做于伯涛的太太。台下一阵惊叹、惋惜声之后，众人羡慕的眼光齐看向于伯涛。于伯涛牵起筱菊花的手，向来宾深深一鞠躬，表示筱菊花未来将在临城开班授课，免费将京剧艺术传授给家乡子弟。如雷的掌声把晚会带到最高峰，也让于伯涛夫妻的鳒鲽情深，在乡亲心目中留下深刻的印象。
　　于伯涛拥有如此美眷，自是春风得意，然而他对筱菊花的宠爱，却引起二太太王采伶的嫉妒。于伯涛的元配许韵芝，知书达理，和伯涛是媒妁之言的婚姻。由于许韵芝结婚多年没有生育，于伯涛又娶了出身交际花的王采伶。王采伶进门后，很快地帮于伯涛生了儿子，从此母以子贵，恃宠而骄。三太太筱菊花原名叫姚可人，可人为偿父债，嫁给对她情有独锺的于伯涛。原本以为一场交易的婚姻不会幸福，没想到伯涛的体贴、仁厚，让可人爱上了他，二人沉浸在幸福甜蜜中。
　　伯涛有了新人忘旧人，激起采伶的妒火。不但在于母面前中伤可人，并设计陷害，制造可人和师兄丁佑民之间，有不清不白之假像。伯涛起初不信，但经不起采伶的一再挑拨，和于母维护门风之压力下，终于将可人和丁佑民拿下，关在柴房，俟天亮后，移送祠堂，听候公审。
　　采伶唯恐奸计被识破，连夜放走可人和丁佑民，并备妥船只，将二人送离临城。可人自认清白，不肯离去，丁佑民情急之下，将可人打昏。可人醒来，发现置身船舱，且船已驶离码头，忙命船夫调头。在此同时，伯涛得知二人逃脱，率韵芝、采伶和家丁多人寻来。
　　韵芝命家丁泅水把船拦下，采伶心虚，刻意阻止，“于伯涛”和“姚可人”陷入天人交战。而在船上的可人，见船夫不肯调头，大喊救命。不料已被采伶收买的船夫，却放火烧船，自己跳江泅逃。轰然一声，整艘船火光爆开，熊熊火光下，可人、丁佑民随着船只残骸消失在江面。
　　六年后…
