The real world

A man in a clerical robe stands at a pulpit in a church, preaching to a seated congregation, before the scene shifts to a green-tinted, post-apocalyptic version of the same church where the congregation is now zombie-like and the man is crucified on the pulpit. The final scene shows a dilapidated, overgrown street with a "Saladworks" sign, where two figures walk past the ruined buildings.
