Here's the official synopsis for Brothers by Blood:
In the City of Brotherly Love, eight-year-old Peter Flood helplessly watches on as his little sister is killed by a neighbor's reckless driving. Tormented with grief and resentment, his father finds revenge as the only solution, leaving lasting generational wounds. Thirty years later, Peter (Matthias Schoenaerts) still wrestles with the guilt he feels over his sister's death and his father's vengeance. As he tries to distance himself from the criminal family business, his cousin, Michael (Joel Kinnaman), becomes more powerful in the hierarchy. Bonded by blood, neither man can escape violence as they are dragged further into a chilling cycle of betrayal and retribution.
Written and directed by Jeremie Guez and based on the novel by Pete Dexter, Brothers by Blood also stars Maika Monroe (It Follows) and a suitably gruff Ryan Phillippe. It looks grim and tense and even a little frightening - there are a few truly shocking images in the trailer.
Brothers by Blood arrives in select theaters and on VOD and digital platforms January 22.
