Something is strange about Freddie Figg's babysitter - they don't usually bring a balaclava...
It starts out like a normal night for Freddie. His parents are heading out and they've got a babysitter coming in. But Freddie knows there's something a little off about this little old lady - and it's not just her moustache. Can Freddie convince his parents of the threat "she" poses, and can he save his home from being burgled?
