Stephen Graham delivers what critics are already calling a career-defining performance in the chilling new psychological thriller Good Boy.

The story follows a seemingly ordinary suburban father whose teenage son is suddenly arrested for a brutal murder. As the family’s perfect life begins to unravel, dark secrets, lies, and shocking revelations emerge that force the father to confront an unbearable truth: how well do we really know the people we love most?

With its relentless tension, moral ambiguity, and jaw-dropping twists, Good Boy dives deep into themes of family, guilt, denial, and the terrifying gray area between right and wrong. Graham’s intense, layered portrayal of a man desperately trying to protect his family while hiding his own demons has been described as “mesmerizing” and “devastating.”

If you love dark, intelligent British crime dramas like The Stranger, Broadchurch, or The Pact, this one is going to hit hard.
Good Boy is coming to screens in 2026 — and it already looks like one of the year’s most intense watches.
