De rouille et d’os, by Jacques Audiard (2012, French with English subtitles, 2h03mns)

Ali finds himself with 5-year-old Sam in his arms. It’s his son whom he barely knows. With nowhere to stay, no money, and no friends, Ali seeks refuge at his sister’s place in Antibes. There, he feels much better instantly. She welcomes them in the garage of her summer house, takes care of the young one, and the weather is good.
Following a fight in a nightclub, fate leads him to cross Stéphanie’s path.  He takes her home and gives her his phone number.
