Tagline: oh hum.

In the near future a glum young man with designer fuzz goes about his dreary business in a barren cityscape. His blank look never changes. Italy is under siege both within as well as from without. He lives alone in Safe Zone 13 (his wife is in Brazil on business and can’t return because of the crises) and we see only two other residents and hear references to a few more unseen.
We learn this much by flashbacks that are poorly sign posted and confusing as the characters wear the same clothes and look the same in the flashback past as the current present. Don’t film school schools teach techniques to signal this distinction?
No, I never did understand the title. What some of it did was to bring to mind the last days of Salò Republic late 1944 or the Hot Autumn of the so-called Red Brigades of 1969.
Oh, and I would hardly call it SyFy but the IMDb does. It is a fiction set in an alternative present.
