Police officer Sara Myall and security guard Henry Campos arrive at an abandoned show home on the Texas border to investigate a break in, only to discover a wounded mother and her ten-year-old son Gio taking shelter after crossing the Mexican border. But when the murderous cartel leader Marcus arrives and demands Gio is handed over to him, it is clear that Gio is no ordinary child. He harbors a dark, supernatural power that Marcus wants for himself. Trapped inside the house as more gang members arrive and threaten violence, Sara and Campos must choose between giving the boy up or fighting for their lives.
