Manchester by the Sea (2016)

Lee Chandler is a brooding, irritable loner who works as a handyman for a Boston apartment block. One damp winter day he gets a call summoning him to his hometown, north of the city. His brother's heart has given out suddenly, and he's been named guardian to his 16-year-old nephew.

As if losing his only sibling and doubts about raising a teenager weren't enough, his return to the past re-opens an unspeakable tragedy.
