I couldn't tell you to be honest!
It is set across about 30 years, and it is VERY confusing! At 2 hours 30 minutes.
They do lots of things, get locked up, do drugs, kill people, , have sex, swear alot, Gangstar fair! Not very good to be honest, best bit is the Credits where you get 'I heard it through the grapevine'
It apparently highlights lots of significant Italian Events, but I found it to be bland.
Though I did see the amazing Shane Meadows film 'This is England' that day! And nothing will top that for a while.
