It is the late 1950s and in lower middle-class Toronto, Audrey Prendergast, whose love for her family blinds her to all else, sees the new medium of television as the only means of climbing the social ladder. And climb it the Prendergasts begin to do when Audrey launches a children’s show called Rumpus Room, starring herself as Miss Mary and her young son Henry as Bee Good/Bee Bad. When the program becomes an overnight sensation, and the Prendergasts’ world begins to change, much to the chagrin of Audrey’s husband, Peter, family comedian and would-be novelist. Determined to keep his family anchored in reality, Peter refuses to have anything to do with Rumpus Room and throws all his energy into writing his novel and doing an almost non-stop and hilarious commentary on modern culture.
