From NetFlix:

A corruption scandal fractures a family of New York City cops
in this generational drama about homicide detective Ray Tierney
(Edward Norton), who’s tasked with investigating a precinct run
by his brother (Noah Emmerich). As if that weren’t enough, Ray’s
fellow officer and best friend (Colin Farrell) may turn out to
be dirty. Directed by Gavin O’Connor, the film features a
high-octane supporting cast that includes Jon Voight and Jennifer
Ehle.

At first this film seemed ho-hum, another corrupt cop story. But stay
with it! The ensemble work and acting are powerful. Colin Farrell has
often played a crook or murderer with a conscience, but this time he
is corrupt with no turning back. Hereafter I will remember the name
Noah Emmerich (Yale, NYU Film School, Law and Order, etc). Since I
first saw Jon Voight in “Midnight Cowboy” he has changed a bit. How
time flies.

The film is very VIOLENT, no children allowed.

Wow!
