Aziraphale’s good deed of picking up a hitchhiker on his way back to Soho, proves to be a serious mistake. In 1941 Crowley and Aziraphale encounter some surprising adversaries, old and new, as the Nazi spies who almost entrapped Aziraphale return as Zombies from the dead, intent on preventing him from attempting a Bullet Catch on the West End Stage.

Aziraphale tries to bring Maggie and Nina together by organizing a meeting of the Whickber Street Shopkeepers and Street Traders Association. In Hell, Shax is determined to launch a full scale attack on the bookshop, with a legion of demons at her command. Nina's heart is broken, as is a bookshop window. Gabriel has a close encounter with Mrs Sandwich and a small plate of cakes.

Crowley becomes a Heavenly bee and learns the truth about the Armageddon sequel. Aziraphale defends his bookshop from Shax's army and reveals his halo, Maggie and Nina become warriors, and Jim the assistant bookseller gets some hot chocolate. Crowley and Aziraphale get to the bottom of the mystery of the Matchbox. The Metatron brings an oatmilk latte, along with a final offer.
