A painful truth sets Jeremiah's course while Sims prepares to attack the Alliance. Markus and Kurdy must combat enemy forces outside and within Thunder Mountain itself to protect a future worth living in.

Mister Smith shows Jeremiah and Kurdy a refuge for children who will need protection if war comes, which seems inevitable as Daniel's forces surround Thunder Mountain. The key to victory may lie in the revelation of secrets. 

Jeremiah joins Kurdy and Mister Smith on a delivery job.

Big Death survivor Frederick Monash knows something important and Devon, it seems, knows him. Thunder Mountain wants to find Monash before Daniel's forces can kill him and Jeremiah wants to know if he can ever really trust his own father.

Was the past the best of times or the worst of times? It depends on whose past. Kurdy has to trust Lee when he returns to a town—and a load of trouble—he left behind while Jeremiah is imprisoned in an idealized replica of the days before the Big Death.

Mister Smith is confident for a miracle; the people at Thunder Mountain are concerned with the army Markus is building.

Wanting to savor his dish of vengeance while it's hot, Jeremiah joins Markus and Kurdy in a sting to smoke out Daniel's raiders. In Milhaven, Mister Smith gives Erin a disquieting message from God.

Thunder Mountain is bringing new towns into the Alliance, drawing Daniel's attention and bringing Mister Smith a vision too awful to contemplate.

Adam comes to Milhaven to kill Jeremiah and nearly succeeds, sending Jeremiah, Kurdy and Mister Smith on a dangerous mission into one of Daniel's strongholds.

While Kurdy tries to unravel the mysteries that surround Mister Smith, Jeremiah has a "High Noon" encounter with the citizens of Milhaven when some of Daniel's disciples storm into town.

Jeremiah prepares for an awkward reunion with his father, Devon. Libby gives Jeremiah a letter from Devon, written years ago, which explains what happened the day he and his wife disappeared.

Markus struggles to achieve consensus among the factions that could re-build the country. He sends Kurdy with a new partner to rescue some of the delegates who have fallen into very tough hands.

After a brief reunion with his father, Jeremiah returns to Thunder Mountain, where he finds Kurdy still holds him responsible for Elizabeth's death. Markus assigns them to separate -- and equally dangerous -- parts of a mission to free the leaders who were taken prisoner before their captors can carry out a standing execution order.

Kurdy, Lee and Meaghan work to free Jeremiah, Markus and the others from Valhalla Sector.

Yet more questions and few answers, Mister Smith is here, yet he is not. Kurdy is scared, yet fearless. Jeremiah is weak, yet strong. A father and son are reunited only to be thrust apart. More about Valhala Sector and their evil plans is revealed.
