The year is 2258, ten years after the destruction of Earth by the Minbari fleet. The last refuge of Humanity is a devastated colony on the planet Proxima-3. President Mary Crane is the head of the Resistance Government. The remnants of the Earth Military continue to fight against the Minbari using raiding tactics. Relations with the Narn allies are far from ideal. The last hope of Humanity is one single ship and one single person. This ship is the Babylon, this man is its captain. John Sheridan.

Sheridan is betrayed by the Narn administration on Vega-7 and captured by the Minbari. He is brought before the Gray Council. A woman who inexplicably entered his cell asks him a mysterious question: “What do you want?” With the help of her mysterious companions, Sheridan escapes and takes with him a hostage - Satai Delenn from the Gray Council.
