The outrageous fun begins when ruthless media mogul Rod McCain (Kline) acquires England’s Marwood Zoo. Determined to transform the quaint, little zoo into a money-making attraction, McCain sends his sexy marketing executive, Willa (Curtis), and his lecherous son, Vince (also Kline) to whip the place into shape. Upon arrival, however, they discover Marwood’s straight-laced director, Rollo (Cleese), has already implemented his own harebrained scheme to boost attendance: from now on the zoo will do away with cute, cuddly animals and display only "fierce creatures."

Things take a wild and woolly turn when the outraged zoo keepers, led by insect expert "Bugsy" Malone (Palin), launch a riotous revolt to save their furry friends!
