Koskay tells Faye and Finn the story of his occult researches- and forces Faye to choose which of Mercy's sons will be destroyed to complete his victory. It is also revealed that Jeff is Lucas' father.
Faye and Finn are reunited with Lucas- but in a locked cell, at the mercy of their captors. Meanwhile, Jimmy's leg has healed with supernatural speed, and he and Liz decide to look for their friends.
At the mine entrance, Faye and Finn find what's left of Silver Cross' inhabitants- gaunt, shuffling mine workers who look barely human. Having made their way underground, Finn suffers from the effects of silver on his werewolf half- and then they are captured by the shadowy Mr. Koskay.
Finn and Faye begin to explore the town, and meet Jeff- an old man who works for a Mr. Koskay. He tells them silver is being mined in Silver Cross by Koskay- but denies all knowledge of the murderous creatures.
Faye and Finn make their way to the deserted ghost town of Silver Cross. As they enter the town a sleeping Faye is jolted out of another mysterious dream by a terrifying ambush, as misshapen humanoid creatures attack their car.
Back in Winter Mill, Liz and Jimmy are following their friends' progress. Jimmy realizes that the trail they've been following looks much like the historic Silver Trail; he guesses that the kidnappers are making their way into the heart of the old silver mining territories.
The insects begin to find their way in to the motel, and Faye and Finn are forced to leave. They make it to the car, and finally leave the swarm behind. But when they catch up with the Black Dogs, they find that the trail has gone cold.
