When the bones of a man found in a subway tunnel are identified as a sandhog miner named Donavan who disappeared in 1947, Lilly and Valens believe that he may have been murdered.

During 1947, the rumor mill was abuzz about why Donavan went missing. Maybe it was because of his attempt to unionize his fellow miners or his public affair that didn't sit well with the locals. There was a long list of suspects, including the owner of the mining company who wanted to stop the impending strike, and a fellow sandhog who wanted nothing to do with fighting for anyone's rights. Meanwhile, Joseph tells Lilly he loves her.
