Trust Me, I'm a Troublemaker

Archie is a very mature child - some would say far too mature! Having grown up with his gran, he seems to have acquired some adult ways - and the kids at his new school find them unbearable. Especially Miranda - the class troublemaker. At first she absolutely can't stand Archie, but then she starts to see him as a bit of a project - could she really make Archie into a troublemaker extraordinaire? Their unlikely friendship really gets going when Archie needs help to scare off his dad's new girlfriend....
