Antonio Moreira's textile factory owed much of its success to worker Harry Lage, who had established new operating guidelines. Lage sought out Moreira, hoping to be rewarded for his efforts, but he received no response; a heated argument ensued between the two. Unsuccessful, the disoriented worker shot his boss and fled. Manager Mirtos, Moreira's enemy, framed Lage and provided the police a clue: a tattoo on the worker's arm.
