LOS ANGELES, Oct 19 — A24 has released the first trailer for its upcoming western drama The Ballad of Lefty Brown that stars Bill Pullman.

Pullman stars as a merciless cowboy who sets out on a journey to seek revenge after his long-time partner is killed by a rustler. The film also stars Kathy Baker, Jim Caviezel, Tommy Flanagan, Peter Fonda, Joe Anderson, Diego Josef, Michael Spears and Lewis Pullman.

The synopsis of the film reads: "When cowboy Lefty Brown (Pullman) witnesses the murder of his long-time partner — the newly-elected Senator Edward Johnson (Fonda) — he strikes out to find the killers and avenge his friend’s gruesome death. Tracking the outlaws across the vast and desolate Montana plains, Lefty recruits a young gunslinger, Jeremiah (Josef), and an old friend, a hard-drinking US Marshall (Flanagan), to help deliver the men to justice.

"After a gunfight with the outlaws leaves Jeremiah wounded, Lefty returns home with the names of Johnson’s killers only to find that he is being accused of his friend’s murder. With the tables turned, and with his friend in the governor’s mansion (Caviezel) refusing to help, Lefty must evade the law and prove his innocence by exposing the powerful men ultimately responsible for Johnson’s death. A thrilling and action-packed Western, The Ballad of Lefty Brown is a story about loyalty, friendship, and the relentless pursuit of justice.”

The Ballad of Lefty Brown is set for release on December 15.
