A strange black rain covered the small town of Bixby like a shroud. Warm, thick drops cling to the skin, seep through clothing, leaving their mark everywhere. And anyone who gets caught in this downpour changes. People begin to overflow with hatred, rage, cruelty, and an insatiable thirst to kill everyone who managed to stay dry. Friendly neighbors turn into deranged maniacs. People who were in line outside the cinema burst into the hall and deal with helpless viewers there. And only a few people, for different reasons, remain in their right minds. Now the lives of these people turn into a survival game with a completely unpredictable result, and the only path to salvation is to find the source of the curse that struck Bixby—and at the same time not to get caught in the rain, because resisting its effect is impossible.
