Bobby and Spader become employed as bellhops there, and investigate the ties between First Earth's Turning Point, rival crime godfathers Max Rose and Winn Farrow, and the Nazi party.

The Traveler of Third Earth, Patrick, accesses a computer that predicts the future in which they save the Hindenburg: industrial spies working for Max would lead to the Nazis developing an atomic bomb and disastrously winning World War Two.

Bobby and Gunny return to First Earth, only to find that Spader and Rose have gone ahead, seeking to stop Winn Farrow from shooting a firework rocket into Hindenburg.

Bobby was flown to the LZ-129's launch site by a female aeroplane pilot called Nancy Olsen (Jinx), who has been his friend and client at the hotel.

While on Third Earth, the young Traveler learns that Max Rose was destined to die on the same highway, on the same day, after crashing into a motorcycle cop.

Gunny arrives in a limousine with an elderly man claiming to know Bobby's great-grandfather (unknowingly referring to Bobby when he was on First Earth), and explains how Uncle Press had died, describing how an accomplice (who the Gangster revealed to be Saint Dane) persuaded Tony, the gangster's partner, into shooting a Tommy Gun into the flume.
