The Sleepover Club at Kenny's : meet my sister, Molly the monster

Join the Sleepover Club: Frankie, Kenny, Felicity, Rosie and Lyndsey, five girls who just want to have fun -- but who always end up in mischief! Laura (otherwise known as Kenny) is fed up with her older sister Molly's tricks and, with the help of the Sleepover Club, she decides to teach her a lesson. But Molly has an older, wiser and wittier ally. Will the Sleepover Club be a match for Molly and her secret weapon?
