"No Surrender, No Retreat" was the overall title of Babylon 5's fourth season. The first chapter of this saga, "The Hour of the Wolf," aired in America during the week of November 4, 1996. Picking up where Season Three ("Point of No Return") left off, a thermonuclear explosion has rocked the Z'ha'dum, homeworld of the hated Shadows. In the aftermath of the detonation, B5 security chief Garibaldi is missing, and Captain Sheridan is presumed dead. As a result, the Alliance is shattered, despite the strenuous efforts of Delenn to keep it together. As Delenn, Ivanova and Lyta search for Sheridan, G'Kar combs the skies for Garibaldi. And on the Centauri front, Londo learns that Emperor Cartagia (Wortham Krimmer) has entered into a potentially disastrous deal. "The Hour of the Wolf" was written by series producer J. Michael Straczynski. ~ Hal Erickson, Rovi
