Probationary angel Jonathan (Michael Landon) and his sidekick Mark (Victor French) to reconcile young construction-firm heir Arthur Krock Jr. (Jonathan Frakes) with his eccentric widowed father Arthur Sr. (Ron Moody). It seems that the elder Krock likes to fantasize that he is King Arthur -- and that his latest "quest" is to rescue the residents of an old building complex that Krock Jr. plans to demolish. In the course of events, "King Arthur" meets his "Guenevere" in the form of veterinarian Gwen Halstead (Jean Allison), one of the tenants whom Krock Jr. intends to evict...after seeing to it that his dad is declared mentally incompetent, that is. ~ Rovi
