In English, the title means 'Sunday in August' and it's quite aptly named. It makes you feel like you were eavesdropping on the lives of a few people in Rome, most of whom are stretched out on the beach and a few are struggling with some grave matters in the city itself on a hot Sunday. So it's quite a lot of little stories stitched together into a movie, kind of like little collection of vignettes.
First, there are some local boys getting ready to hit the beach & so race towards it on their bikes. Then, there's a girl trying to make a better life by going out with a richer beau, and in the process snubbing a poorer and uneducated one. The snubbed beau, unwittingly becomes involved in something very sinister in order to make quick bucks. Another story involves a large family (or was it two families?) going to the beach in an old car. There, the teenage daughter of the family meets a boy from their own locality. Yet another story involves two single parents exchanging parenting tips and phone nos. (& maybe more in future?). And there's Marcello Mastroianni in one of the stories. He plays a traffic cop and a devoted boyfriend to his pregnant girlfriend who's lost her job because of conceiving a child out of wedlock.
All stories are good in their own way. But unfortunately, the movie suffers from the same problems as any movie with a huge cast of characters does. In the end, none of the stories made any impact because the characters could not be sketched out properly in the limited time. So, things gets resolved very quickly, ending on a happy or sad note; only you can't really be expected to care with such little character development.
Mildly interesting but don't have very high hopes.
