Dr. Larry Flienhart literally returns to Earth after four months on the International Space Station, discovering through long chats with Charlie that he has a long way to get his physical and metaphysical feet back on terra firma after his voyage of discovery turns into one of self-discovery. Meanwhile, the brothers use math analysis to probe into the mind of a notorious hit man, awaiting execution in San Quentin, who offers to solve a murder he says he committed during a kidnapping -- and find out why his story has a big hole in it.
