The film tells the story of two twins separated in childhood who reunite when they are older. One of them has grown between outlaws and has become one of them, a murderous bandit who frightens the region. The other has grown, without knowing it, in exactly the ranch of the man who murdered his father and has become the loving foreman of the farmer's daughter, now deceased.
Unfortunately the movie Calibre 44 is not yet available on HBO Max.
