Anna (Christina Ricci) has just been in a terrible car accident and feels like she's been left in the dark until she slows down. When she slowly regained consciousness, she was surprised to find that she had been judged dead, because her funeral was being prepared, and the funeral director Elliot Deacon (played by Liam Neeson) was preparing for her burial. , Anna knew that once she was sent into the coffin, she would be buried alive, so she appeared to Elliot in the form of her soul, hoping that he would believe that she was still alive, and did not want to face the bottomless darkness. Elliot insisted on his professional judgment, thinking that seeing Anna was only because of his psychic ability, and persuaded her to leave with peace of mind. Boyfriend Paul (Justin Long) always believed that Anna was still alive. He believed that Elliott was not as understanding as he appeared on the surface, and insisted on investigating the cause of Anna's death, which finally made him gradually approach the truth, but Anna has gradually moved towards another world
