When you're seventeen and in love, it seems that only cloudless happiness lies ahead. The roar of the engine, the track, the wind in the face, and behind her back is the best girl in the world. But everything changes in an instant: Fedor and Alena get into an accident. Fedora puts dead water on his feet. It is mined in Zaruchye, an anomalous zone in the Vologda region. Different entities live there: mavkas, mermaids, leshaks and others. In Zaruchye, the road is open only to walkers - people who have undergone special training. Alena remains in a coma. Her father is sure that living water can save Alena. But nothing is known about this water: all the walkers who went deep into the Zaruchye disappeared without a trace. Fyodor is not stopped by rumors about the dead, and he goes to Zaruchye for living water. Now a gloomy forest, terrible evil spirits and a path into the unknown await him. But Fedor must pass it, because there is no choice: he is obliged to bring to life his beloved, who is dying through his fault.
