From IMDB:

Following a raft of shootings in an English market town, the crimes are retold through the eyes of a journalist and the tragedies’ victims.

Netflix Steaming offers 4 episodes of so-called Season 1. However, as far as I can tell the story ends with the fourth episode.

After watching the miserable life of the long-suffering shooter so that we understand why he goes berserk, we get to know some of the inhabitants of the sad, small British town Southcliffe. David Whitehead, the reporter who is also a native of Southcliffe and who has bitter memories of the town, is the center of the story as he digs for information and interviews various townies. There are two guilty provocateurs, each with his own reaction to the shootings.

Basically this is a very depressing story with not a bit of sunlight visible, despite the fact that it is very well done. You are warned.
