If a health insurance company unfairly denied coverage to a patient who needed it, it’d be easy to empathize with someone who decided to exact revenge on his behalf. In Rodrigo Plá’s thriller, a woman (Jana Raluy) does just that, gradually confronting each person in the chain of command of the insurance company that refuses to assist her dying husband. While some of the plot points in this Mexican drama strain logic, there’s an undeniable emotional truth to every step the woman takes; the icy, formal cinematography assists by accentuating her helplessness against a faceless bureaucracy. By the time she realizes all she has done is for naught, the executives and their employees are already hard at work erasing any trace of her. In Spanish with subtitles.
