As a mysterious, life-threatening illness overtakes Ambassador Londo Mollari, Dr. Franklin makes a shocking discovery: the condition is psychosomatic, a physical manifestation of a soul ravaged by guilt. Trapped in a delirium of his own making, Londo is forced to confront the ghosts of his past crimes in a battle where the prize is his own survival.

Meanwhile, Lennier's quiet anguish reaches its breaking point. Tormented by his forbidden love for Delenn, he makes a fateful and desperate choice: to silently disappear and join the Rangers on the frontline—a path of certain death for one so unprepared. As two souls fight their most intimate wars, the fate of one hangs on accepting his past, while the other's depends on abandoning his future.
