Out-of-work reporter Leng Ruixu is desperate, so he rents the notoriously haunted apartment 302 for next to nothing. But every night at midnight, his bedroom door swings open by itself. Its creak cuts through the silence, and a pale gray mist seeps through the crack, carrying the white silhouette of a woman in a red dress. Her outline is exactly like that of his younger sister, who vanished under mysterious circumstances six years ago!
Blood seeps from the cracks in the walls, white hair is hidden in his shoes, and a child’s sobs echo through the corridor. Every eerie sign points to that dark red wooden door that seems to “breathe.” Worse still, strange markings appear on his left arm and creep along his veins toward his heart. His sister’s apparition grows fainter by the moment, as if the door will swallow her whole at any second.
The secrets of a family curse, the truth behind urban legends, and the abyss behind the door that devours souls leave him with no choice but to risk his life. He must either open the haunted door himself and venture into eternal darkness to find his sister, or watch her vanish for good as he becomes the next sacrifice!
