Allie loves baseball. It's the one thing that has been consistent in her lately complicated life. Allie's father left recently, and now Allie has a new family -- her mother's new girlfriend, Phyllis, and son Miles have moved in. It's taking some adjustment, mostly because Miles seems determined to get under her skin. Things start looking up when Allie gets invited to join the boy's baseball team as their new pitcher. But then Miles announces he's quitting the boy's team and tries out for Allie's old team -- a girl's team!
