Babylon 5: The Corps is Mother, The Corps is Father... (1998)

Synopsis
Bester (Walter Koenig) doggedly pursues a murderous telepath who killed a friend of his. He takes this opportunity to provide valuable on-the-job training to a pair of rookie Psi Cops. Since the focus is on Bester, virtually none of the Babylon 5 regulars appear, with the exceptions of Jeff Conaway (Zack) and Richard Biggs (Dr. Franklyn). Best moment: the Psi Corps training film, a marvelous piece of ersatz propaganda. First broadcast on April 15, 1998, "The Corps is Mother, The Corps is Father. . ." was written by J. Michael Straczynski. ~ Hal Erickson, All Movie Guide
