Jackie Coogan takes over from Ray Bolger in the role of Shirley Partridge's father Mr. Renfrew (now named "Walter" rather than "Fred"), while Rosemary DeCamp recreates her portrayal of Shirley's mom Amanda. The plot gets under way when Grandma Amanda goes to work as the Partridge's maid, if only to escape the rampant chauvinism of Grandpa Walter. Shirley (Shirley Jones) tries to patch up the argument between her dad and mom, succeeding only in sparking a gender-supremacy argument that divides the entire family. Finally, Reuben (Dave Madden) is enlisted to resolve the issue--but this requires him to impersonate a burglar! Songs: "Workin' on a Groovy Thing" and "Grandma". ~ Hal Erickson, Rovi
