Quick recap
On Max's birthday, he and his brother Noah find an old mirror in the attic. When Max pulls the light's chain, he turns invisible. It becomes a game with his friends, and each round lasts longer. Erin and Zack come back acting strange, and Max learns why: their reflections have taken their places, and the real kids are trapped in the mirror. Max's own reflection tries to swap with him, and the copies chase him through the house. Lefty smashes the mirror with a softball, the reflections get sucked back in, and Erin and Zack return. At the end, Max plays catch with Lefty and notices he's throwing right-handed now.
