Rufus and his sister Alexa hate each other at the best of times. When Rufus's friend Phil manages to hypnotize Alexa, Rufus is ready to enjoy the power. They begin by ordering Alexa to be kind to her parents and Phil. The plan backfires when Alexa sweetly suggests canceling an expensive family vacation in favor of a week at home playing board games. Then Alexa turns on the charm with Phil, and suddenly Rufus has to deal with a lovesick amateur hypnotist. Rufus is certain it can't get any stranger until Alexa, still in her hypnotic state, is kind to the brother she's always hated, and Rufus is more confused than he's ever been.
