Josh's life has just fallen apart. His father will no longer be coaching the travel baseball team and is moving to Florida, forcing his mom and little sister to move into a small apartment on the wrong side of town. To make matters worse, the new coach of the travel team is an unforgiving drill sergeant.
But then Benji tells Josh of a home-run derby in which the winner gets a brand-new house. All Josh has to do to qualify is hit twenty home runs during his travel-team season. With Benji and Jaden's help, Josh is hoping to hit it out of the park and save his family, because if he strikes out, he may just lose everything.
