In a corrupt Mexican town, rookie police officer Hector is dragged into a bloody battlefield every night, returning with cold weapons and strange “beacons.” After his partner mysteriously disappears, he is forced to hide the soldiers he summons on the streets. Patrolling by day and fighting by night, he must use these bloodstained “gifts” to carve a path to survival through the city’s underworld. When a rusted badge meets an endless arsenal, justice takes root in the cracks.
