In an episode that jumps between past and present, Weir's traumatic history is brought to light, along with the origin of his friendship with Valence and their career in corporate espionage. In the present, Weir and Hailey's tenuous relationship begins to thaw—but does her story add up? Not according to the newly resurfaced operative, Dr. Ben Wilson.

Armed with the data stolen from Arda, Weir is in go-mode to unveil the truth behind Valence's shocking death and enlists Hailey’s help to exploit a member of Crowley’s network. Meanwhile, US Treasury investigator Edward Homm may finally be ready to cooperate and help find Crowley. Liv, Weir's ex-wife, is dragged back into his world of secrets, and we see a new side of The Intern, the only member of Weir's original team spared in the explosion.
