A former slave who arrives in Yellowstone City, Montana, a desolate former boomtown now on the decline, looking for a place to call home. On that same day, a local prospector discovers gold - and is murdered.

Described as a tale of revenge, dark secrets, and buried treasures, the film is set against the turbulent backdrop of 1870s Montana. It picks up in the moments before the execution of Isaac Broadway, as he gives his estranged son, Henry, an impossible task: murder the man who framed him for a crime he didn’t commit. Intent on fulfilling his promise, Henry travels to the remote town of Trinity, where an unexpected turn of events traps him in town and leaves him caught between Gabriel Dove, the town’s upstanding new sheriff, and a mysterious figure named St. Christopher.
