This final episode of Moonlighting finds Bert (Curtis Armstrong) and Agnes (Allyce Beasley) getting married, just as David (Bruce Willis) is breaking up with Annie (Virginia Madsen), the cousin of his partner and former lover Maddie (Cybill Shepherd). At the same time, the Blue Moon Detective Agency closes its doors, whereupon ABC network executive Walter Whitebread (Mark L. Taylor) solemnly begins dismantling the set. An eleventh-hour effort to save the Agency--and the series--is foiled by the demographic evidence supplied by big-time Hollywood producer Cy (played by Dennis Dugan, billed under his Moonlighting character name of Walter Bishop). Even worse--the Anselmo Case (you remember the Anselmo Case) may never be solved!
