In 1930s Philadelphia, twelve-year-old Jimmy Frank and his best friend Lola live across the street from Shibe Park, home of the Philadelphia Athletics baseball team. Their families and others on the street make extra money by selling tickets to bleachers on their flat rooftops, which have a perfect view of the field. However, falling ticket sales at the park prompt the manager and park owner to decide to build a wall that will block the view. Jimmy and Lola come up with a variety of ways to prevent the wall from being built, knowing that not only will they miss the view, but their families will be impacted from the loss of income. As Jimmy becomes more and more desperate, his dubious plans create a rift between him and Lola, and he must work to repair their friendship.
