To complicate matters Christopher and Daniel Sterling, the two boys he asked to help repair his ship, have run into problems of their own. A local bully is determined to beat them up, their crazy Uncle Cenric has just framed their dad for stealing billions of dollars from the US Treasury, and now they have to explain the whole thing to their mother! What could be worse than that?
