Season 3 - Episode 8 "Bad Day at Black Rock"

The Colonel, bloody and battered, returns to the Whitespring,
discovering that MODUS has indeed been busy during her long absence
with plans of his own. While Stein arrives at the PACT as MODUS’
representative…to negotiate an alliance and a place in the new
future they plan to bring about, only to find himself confronted
with his own past. Deep in the Savage Divide, Trader Red and her
companions continue their trek south, but little do they realize
that a wolf in sheep’s clothing walks beside them…and what dangers
now await them. And across Appalachia, separate factions begin to
gather their resources and take actions of their own against a
growing storm. Against growing odds, the region prepares for
war.
