Charged with living on her own for the first time in her life, Rosa Dimaano (Alessandra de Rossi) takes a job as a maid in Singapore, where she works for the family of a mentally challenged boy. But little does she know that her arrival coincides with the eve of the seventh lunar month -- long believed to herald the opening of the fiery gates of hell. Filmmaker Kelvin Tong directs this record-breaking blockbuster Filipino thriller.
