A bounty hunter from Joe's past arrives in Midnight to punish him for leaving the angelic fold. Manfred takes charge with a plan to lead Fiji, Olivia, Bobo and Lem in an effort to stop this dangerous, nearly immortal foe from killing Joe and Chuy, as well as destroying Midnight. Meanwhile, Creek struggles to recover from her family tragedy. Elsewhere, the Rev refuses to compromise the safety of his neighbors and it costs him dearly.

An apocalyptic sandstorm engulfs Midnight concealing wraith-like demonic spirits heralding the arrival of a demon from Hell. Fiji knows this demon wants her and Bobo vows to protect her, while wondering why the demon has targeted Fiji and no one else. Manfred, Joe and the Rev dig for answers from the past, but when the storm gets too dangerous, Manfred leads the Midnighters to an unlikely hiding spot outside of town. Olivia confronts Lem about their relationship, and Creek helps Manfred when he needs it most.
