The team travel to Chicago, 1927, to prevent a timequake and find Damian and the mysterious speedster responsible... and they've teamed up with Malcolm Merlyn. As the villains try to regain the amulet the Legends took from them, Mick is plagued by hallucinations of an old friend. Meanwhile, Martin reveals the existence of his daughter to Jax.

While the Legends deal with Martin's daughter and try to work out the identity of the speedster opposing them, Malcolm and Damien have their own demands for Eobard while trying to tap into Rip's memories.
