After a recent development disorder leaves him much shorter than he used to be, Reese has become academically demotivated, and worries he won't receive his diploma in his final few weeks of high school. But his sister, a recent college graduate who's twice as tall as him, moves back home. Her arrival sparks a change in Reese's attitude to start treating his family - and particularly his amazon of a sister - a lot nicer than anyone would reasonably expect. Eventually his sister realizes she might be able to save him from failing his senior year, and Reese does his best to more than thank her in return.
