Malcolm Mitchell is a kid with problems, not the least of which is an overbearing sister who is supposed to act as his mom when Mom is out of town. She’s eighteen and obsessed with her own interests, interests like her friends and her boyfriend, the older Cade, who really only has one thing on his mind. It was supposed to be a weekend at home, Mom out of town and Savannah playing the mom. Of course Savannah goes on a tirade all because she can’t spend time with her friends in the park and has to babysit. She kicks Malcolm out of the house telling him to play in the yard but as she throws his silly magic wand toy out at him everything takes a turn. The wand pops open on one end and an ancient looking slip of paper falls out. This paper instructs how to change anything using this wand. Unfortunately after trying it, Malcolm realizes it probably was a joke and the wand is just a toy. That doesn’t stop him from going on a walk, angry at Savannah, blowing off steam. Even if he’s kidding around when he uses the wand against some people who annoy him, Malcolm doesn’t seem to notice just how well it works after he walks away. In the end Savannah will get exactly what was coming to her and even Cade might get what he always wanted as karma seems to find the older Mitchell sibling quite quickly.
