Watch MoviestoWatch. A tremendous congestion hits the Rome highway ring. The biggest traffic jam ever seen lasts more than 36 hours. At the beginning the people blocked in their cars react normally. But as more time passes, the more we witness personal dramas, hysteric reactions and other grotesque situations. All the episodes are linked as if in a single plot. Cars and their hosts are a microcosm of stories part of a larger universe: the congestion.
