Burbank, summer 1985. Young Howie and his friends have lost a baseball belonging to Howie's father. It's a unique baseball in that it has Babe Ruth's autograph. Kate and George determine, through mathematical and physical laws, that the ball entered a house. Apparently Mrs. McGregor left her door open when she left for the store. So the valuable baseball is in Mrs. McGregor's house. When Kate and George call her the next day, they learn her house has been stolen.
