1955 year. You are a night-shift security worker in a small apartment building protected by D.D.D. protocol.

Behind thick bulletproof glass, in a narrow booth — resident list, blank entry forms, intercom switch, door lever and large red CALL D.D.D. button.

The real Francis Mosses already entered the building at 6:17 a.m. today.

This one is not him.

And he keeps coming back.

Today he brought flowers.
