Rocco's weird mum is dying, and as the loving son that he is, he goes back to Ortona and takes care of her. Rocco's dad and brothers are only slightly objecting to his presence, and while mum's dying Rocco phones Tommy to tell him to come and say goodbye. The Tommy character is possibly the worst of this dismal series. It's absolutely impossible to understand what his motivations are and why he's so schizophrenic. He says he "loves" Lucia, a woman he pimped out, and then he explodes in burst of violence and drinks himself to stupor.
Anyway, after having told Rocco from Paris that he will not visit his dying mother, with another jump in time and space Tommy is shown having bought a bar in Ortona and redecorating it. How fast did that happen? Tommy makes it as far as the hospital's door but doesn't go in to see dying mum. After the funeral weird things happen, one of them being Lucia entering the cemetery with son Claudio to embrace Rocco, only to be sent to Tommy, who's hiding away among some graves. Then an elderly woman appears to "pleasure" Rocco (???)
Finally Lucia and Rocco have a conversation that probably should have been deeply meaningful but it actually boils down to Lucia telling Rocco that he's too violent to his co-stars during their sex scenes. Allegedly Siffredi was infamous for the violence of his scenes, but this does not seem to affect the presentation of his character as a tormented soul.
