The Iron Rider (1920)

When law and order fade into distant memory in Angel City, the townspeople yearn for the era of the Iron Riders, a band of men who took justice into their own hands and brought order out of chaos. The organizer of the group was John Lannigan, whose son Larry decides to take up the mantle of the Riders once again.

Unfortunately the movie The Iron Rider is not yet available on HBO Max.
