2/11: Day of the Dead (2012)
Plot: In this dark Argentinian mystery, a young man named Elías is found wandering along a remote highway, naked and drenched in blood. Soon after, the police discover four mangled corpses in the nearby woods. While the town and the local authorities are quick to blame the traumatized Elías for the murders, his brother Santiago—a local police officer—is the only person who believes in his innocence. Santiago launches a desperate, unauthorized investigation to clear his brother's name, but as he digs deeper, he uncovers a horrific, ritualistic truth involving a local sect and a series of "aberrant" secrets that have been hidden within the community.
