Montana. 1873.
In the moments before his execution, Isaac Broadway gives his estranged son Henry (Brandon Lessard) an impossible task: murder the Sheriff who framed him for a crime he didn’t commit.
Intent on fulfilling his promise, Henry travels to the remote town of Trinity, only to discover that the man he’s come to kill is already dead. But before he can leave, an unexpected turn of events traps him in town and leaves him caught between Gabriel Dove (Pierce Brosnan), the town’s upstanding new Sheriff, and a mysterious figure, cryptically named St. Christopher (Samuel L. Jackson).
As Henry’s quest for revenge turns into a struggle for his own survival, he discovers that his father built the town of Trinity on a dark secret — and a stash of stolen gold that St. Christopher is hell-bent on retrieving. Henry aligns with Dove’s wife Sarah (Veronica Ferres), but to stay alive, he will have to face his father’s demons and the history of violence that threatens to put the town at war with itself.
