Amidst protests from all corners of the universe, Cmdr. Sinclair is ordered to protect Dilgar war criminal Jha'Dur (Sarah Douglas). Notorious for performing experiments on helpless alien prisoners, Jha'Dur claims to have developed an immortality serum. But she may never get the opportunity to use it: Narn envoy Na'Toth has sworn to kill Jha'Dur, orders or no orders. "Deathwalker" made its American TV bow on April 20, 1994; the episode was written by Lawrence G. DiTillio. ~ Hal Erickson, Rovi
