Mum and Mike plan a half-term caravan holiday, but the kids rebel - they want to spend time away from the grown-ups. So when the holiday is cancelled, they find Mum and Mike getting under their feet. It seems the parental tables have turned - so Millie arranges a 'playdate' for them over at Dad and Amber's. Surprisingly, they get on great and a full-on karaoke party follows. Alone at last, Millie, Lauren and Craig can get on with what they want to. But can they manage as well as they think in a parent-free world - especially when a huge storm is brewing..?
