Join the Sleepover Club: Frankie, Kenny, Felicity, Rosie and Lyndsey, five girls who want to have fun -- but who always end up in mischief! It's World War Two for the gang when they get to experience a whole weekend in an authentic wartime house. And when an air-raid siren goes off in the middle of the night, there's creepy-crawlies in the air-raid shelter to worry about too!
