This film captures the unique stresses, joys, and challenges — both on and off the field — for La Liga Spanish referee Miguel Ángel Pérez Lasa. The centerpiece is a Barcelona-Sevilla match, when the filmmakers are given remarkable access, including inside the refs’ locker room before, during, and after the match, intimate isolated camera footage, and realtime audio from their headsets. It’s the best inside look of a top-level referee ever.
