Developed in tandem with his wife’s novel of the same title, Rodrigo Plá (The Delay, The Zone) crafts another airtight thriller, this time taking on a health-insurance system that prefers profit to adequate medical care. Refused treatment that would alleviate her terminally ill husband’s pain—yet not the frustrations of dealing with maddening bureaucracy—Sonia (Jana Raluy) snaps and, gun in hand, single-mindedly goes up the chain of command with a vengeance. The series of increasingly harrowing provocations are interspersed with moments of dark comedy, and coalesce into a final, shocking climax.
