When the Red Rain falls, the world is plunged into chaos. The crimson droplets bring with them a terrifying force that turns people into monstrous creatures, driven by a primal hunger for human flesh. Among the survivors are four kids, forced to confront the harsh reality that in this new world, humans are the most deadly predators. They must navigate the treacherous landscape of ruined streets, avoiding the twisted remnants of humanity that roam the ruins, seeking to devour whatever is left. The survivors are just as deadly as the monsters they've become, and these four young teens must learn to trust each other and work together if they hope to make it through another day. But as they fight for survival, they'll discover that the greatest danger may not be the monsters, but the humans who are still left standing. Will they be able to find a way to reclaim their future, or will they succumb to the brutal savagery that now rules their world?
