No! Nope! Not today! To kids, those are the only words that their parents ever say. But saying no is a part of parenting, right? Well, these siblings disagree. They see their mom as a kill joy who never lets them have any fun. So, a bet is made between the parents and the kids. The parents cannot say no to ANYTHING all day (within reason) or else they loose, and they have to let Katie, the oldest, go to a concert by herself. Now that I think about it, the younger siblings get no benefit from this bet, but whatever. So the tasks range from stomach churning ice-cream eating, Kool-Aid balloon fights, and dressing up like a glitter bomb. Things are going great, but things take a turn. When things get out of hand, everybody realizes that family is the thing that matter most.
