During the Chinese Seventh Month, the gates of hell open and spirits are let loose upon an unsuspecting world. For 30 days, the dead walk among the living. To protect themselves, mortals devise rules. For Rosa Dimaano, all those are just a bunch of old wives' tales. Hailing from a small village in the Philippines, the 18-year-old arrives in Singapore on the first day of the Seventh Month to work as a domestic maid. She urgently needs money to save her sick brother back in the Philippines and ghosts are the last things on her mind. Happily for Rosa, life in Singapore cannot be rosier. Her employers, the elderly and gentle Mr and Mrs Teo, are a godsend, caring for her as if she was their own daughter. Their mentally-handicapped son Ah Soon also takes to Rosa immediately. Between cleaning house and helping the Teos with their work at the Chinese opera, Rosa is blissfully happy....until things start going wrong. Glimpsing strange apparitions at night, Rosa soon finds herself tumbling into the world of the dead. Unknown to the innocent girl, she had unwittingly broken many rules on the first few days of the Seventh Month. As the festivities reach a fever pitch in Singapore, Rosa's life turns into a nightmare. A mutilated boy haunts her. A faceless woman appears. Rosa feels as if she is losing her mind. Her employers urge her to bear with the sightings. But Rosa is uncertain. Someone somewhere seems to be trying to reach out to her. To keep her job, the poor girl has to stifle her screams and fear. To save her brother, she must survive the terrors of the Chinese Seventh Month.
