Jack was the only child at New-Hope Orphanage who did not want to be adopted. When he asked where his mom went, the nuns told him the moon. So Jack threw a fishbowl on his head, made a rocket out of his bed, and got ready to find his mom. Suddenly, despite his best efforts, Jack was adopted by the Robinson Family and forced to make his escape that night, with a little help from his new brother. Jack has to decide between going to the moon and his new brother, Jimmy.
