Babylon 5: Season 4

The five seasons of the series each correspond to one fictional sequential year in the period 2258–2262. Each season shares its name with an episode that is central to that season's plot. As the series starts, the Babylon 5 station is welcoming ambassadors from various races in the galaxy. Earth has just barely survived an accidental war with the powerful Minbari, who, despite their superior technology, mysteriously surrendered at the brink of the destruction of the human race (the Battle of the Line).
