This time, the forest tribes of warrior cats faced a new disaster - drought, which led to famine and shallowing of the stream and lake. The young student Dove, who has extraordinary abilities, learns that the reason for the lack of water is not only the heat, but also mysterious brown animals that have blocked the river upstream. A squad consisting of cats from all four tribes sets out on a dangerous and difficult journey to return water to the lake. But they don’t even suspect what they will have to face. Meanwhile, the ThunderClan healer Sparrow receives a mysterious and terrible omen that promises great troubles for all tribes.
