簡介：This 7-year series chronicled the adventures of the Impossible Mission Taskforce (IMF), a team of government spies and specialists who were assigned "impossible missions" by the unseen "Secretary". Although the cast varied over the years, the main characters included The Team Leader (Dan Briggs the first season, then Jim Phelps the other six), The Techno-Wizard (Barney Collier), The Strongman (Willy Armitage), The Master of Disguise (first Rollin Hand, then The Amazing Paris), and The Femme Fatale (Cinnamon Carter, Casey, Dana Lambert, Mimi Davis).                                                                    　　                                                                    　　The series is best known for its opening mission assignment (conducted by a pre-recorded tape), the theme composed by Lalo Schifrin, the leader's selection of mission agents from a dossier, the opening briefing, the intricate use of disguises and a typical "mask pulloff" scene near the end of most episodes, and the relative lack of characterization of the characters.

簡介：Jim Phelps is the new leader of the Impossible Missions Force, with no explanation, or even reference made, about the departure of predecessor Dan Briggs. First up for Phelps is a mission involving the drug trade. Cresnik and Walters have cornered the heroin market and sell it at a handsome profit to gangs around the world. Phelps devises an operation which will drive a wedge between the heroin dealers and their customers.

簡介：Cinnamon plays a long lost princess to prevent a regent from taking over in 'a small Baltic monarchy.' Of course, IMF's mission is to prevent a dictator from taking over a 'free' monarchy!

簡介：The actors were never told in advance what was in store for their characters. Each new episode was just as much a surprise for them as it was for the viewers.                                                                    　　故事的背景設(shè)定在公元2257年，人類已經(jīng)突破光速，開始大規(guī)模星際旅行及在太陽系附近殖民，與多個(gè)外星文明接觸并有貿(mào)易聯(lián)系。一天，一艘地球聯(lián)邦的星際驅(qū)逐艦在探索未知星際空間的時(shí)候遇到一艘不明星船，因?yàn)檎`判對(duì)方意圖而先敵開火。對(duì)方叫明巴利外星族（Minbari），比人類早進(jìn)化發(fā)展幾千年，其技術(shù)人類無法望其項(xiàng)背。不巧的是地球星船孤注一擲先敵開火的時(shí)候把灰色議會(huì)議長杜哈的給干掉了（那位老兄其實(shí)知道按大設(shè)計(jì)藍(lán)圖，明巴利必須與地球人聯(lián)合并融合，這次到這里也不是閑逛，而是準(zhǔn)備與地球人第一次親密接觸）。于是明巴利對(duì)地球開戰(zhàn)，摧枯拉朽所向披糜，在對(duì)地球本土最后一擊的過程中，明巴利卻突然停止進(jìn)攻并宣布投降。總之，停戰(zhàn)后地球出資在中立空間建設(shè)“巴比倫空間站"，致力星際交流、談判及和平合作。前面四座都被摧毀或莫名其妙消失，于是有了巴比倫5號(hào)。巴5軍頭Sheridan和明巴利大使笛嵐（Delenn）帶領(lǐng)眾嘍羅，聯(lián)合火星殖民地抵抗力量反對(duì)地球聯(lián)邦通過謀殺政變而上臺(tái)的獨(dú)裁總統(tǒng)，聯(lián)合各外星文明反擊神秘黑暗種類——影族（Shadows），向佛隆人（Vorlon）說不，最終走上獨(dú)立自主自力更生的發(fā)展文明道路。

簡介：At the beginning of 2259, Captain John Sheridan replaces Sinclair as the military governor of the station. He and the command staff learn that the death of President Santiago was actually an assassination masterminded by Vice President Clark (who assumed the Presidency upon Santiago's death). A conflict develops between the Babylon 5 command staff and the Psi Corps, an increasingly autocratic organization which oversees and controls the lives of human telepaths. Commander Ivanova, the second-in-command of the station, is secretly a latent telepath who has illicitly avoided registering with the Psi Corps.                                                                    　　The Shadows, an ancient and extremely powerful race who have recently emerged from hibernation, are revealed to be the cause of a variety of mysterious and disturbing events, including the attack on the Narn outpost at the end of 2258. Centauri Ambassador Londo Mollari unknowingly enlists their aid through his association with the mysterious Mr. Morden in the ongoing conflict with the Narn. The elderly and ailing Centauri emperor, long an advocate of reconciliation with the Narn, dies suddenly while visiting Babylon 5. A number of conspirators, including Londo Mollari and Refa, take control of the Centauri government by assassinating their opponents and placing the late emperor's unstable nephew on the throne. Their first act is to start open aggression against the Narn. After a full-scale war breaks out, the Centauri eventually conquer Narn in a brutal attack involving mass drivers, outlawed weapons of mass destruction. Towards the end of the year, the Clark administration begins to show increasingly totalitarian characteristics, clamping down on dissent and restricting freedom of speech. The Vorlons are revealed to be the basis of legends about angels on various worlds, including Earth, and are the ancient enemies of the Shadows. They enlist the aid of Sheridan and the Babylon 5 command staff in the struggle against the Shadows.

簡介：The Psi Corps and President Clark, whose government has discovered Shadow vessels buried in Earth's solar system, begin to harness the vessels' advanced technology. The Clark administration continues to become increasingly xenophobic and totalitarian, and uses a military incident as an excuse to declare martial law. This triggers a war of independence on Mars, which had long had a strained political relationship with Earth. Babylon 5 also declares independence from Earth, along with several other outlying Earth Alliance colonies. In response, the Earth Alliance attempts to retake Babylon 5 by force, but with the aid of the Minbari, who have allied with the station against the growing Shadow threat, the attack is repelled.                                                                    　　Becoming concerned over the Shadows' growing influence amongst his people, Centauri ambassador Londo Mollari attempts to sever ties with them. Mr. Morden, the Shadows' human representative, tricks him into restoring the partnership by engineering the murder of Mollari's mistress while putting the blame on a rival Centauri House. Open warfare breaks out between the Shadows and the alliance led by Babylon 5 and the Minbari. It is learned that genetic manipulation by the Vorlons is the source of human telepathy, as it is later discovered that Shadow ships are vulnerable to telepathic attacks. Displeased at the Vorlons' lack of direct action against the Shadows, Captain John Sheridan browbeats Vorlon ambassador Kosh Naranek into launching an attack against their mutual enemy. Kosh's deeds lead to his subsequent assassination by the Shadows.                                                                    　　Former station commander Jeffrey Sinclair returns to Babylon 5 to enlist the aid of Captain Sheridan, Delenn, Ivanova and Marcus in stealing the Babylon 4 space station and sending it 1,000 years back in time to use it as a base of operations against the Shadows in the previous Minbari-Shadow war. Undergoing the same transformation as Delenn at the end of Season 1, Sinclair transforms into a Minbari and is subsequently revealed to be the actual Valen of Minbari legend, rather than a reincarnation. Spurred by the reappearance of his assumed-dead wife (who now works for the Shadows), Sheridan travels to Z'ha'dum, the Shadow homeworld, in an attempt by them to recruit him. However he instead destroys their largest city in a kamikaze nuclear attack, and is last seen jumping into a miles-deep pit to escape the explosion. Garibaldi, during a fight with Shadow vessels, goes missing.
