Devil's dance

Two men dance on a grassy lawn at night in front of a building with purple lights, one man in a white shirt and dark pants, the other in a dark shirt and light pants, moving rhythmically with arm and leg motions. The scene cuts to two men in clerical attire standing in a doorway, one with gray hair and glasses, the other with dark hair, both looking forward with serious expressions, then the man with gray hair turns and moves out of frame.
