"It's not a river, it's this river. A hot, motionless afternoon. Enero and El Negro are fishing with Tilo, their dead friend's teenage son. After hours of struggling with a hooked stingray, Enero aims his revolver into the water and shoots it. They hang the ray's enormous corpse from a tree at their campsite and let it go to rot, drawing the attention of some local islanders and igniting a long-simmering fury toward outsiders and their carelessness. It's only the two sisters--the teenage nieces of one of the locals, Aguirre--with their hair black as cowbird feathers and giving off the scent of green grass, who are curious about the trio and invite them to a dance. But the girls are not quite as they seem. As night approaches and tensions rise, Enero and El Negro return to the charged memories of their friend who years ago drowned in this same river."--
