When a young woman from the Philippines arrives in Singapore to begin work as a domestic maid, her naïve lack of superstition leaves her an open target for the undead as the gates of hell come blasting open in a terrifying tale of the supernatural directed by Kelvin Tong and starring Alessandra de Rossi. In the seventh month of the Chinese calendar, legend has it that the souls of the damned ascend from hell to walk the Earth; however, there are a series of secrets to avoiding their wrath. From not going for a midnight swim to never turning around when you hear your name called in the darkness and never conversing with strangers on a deserted road, humans can avoid a horrific fate if they simply remain steadfast in their determination to shun evil for 30 days. Rosa (de Rossi) is an innocent, though, and upon arriving for her new job in the seventh month, she carelessly breaks every rule intended to keep the living safe from the murderous powers of the underworld. A box-office hit in its native Singapore, director Tong's homegrown tale of horror arrives stateside to test and fray the nerves of Asian horror lovers who previously suffered sleepless nights as the result of such films as Ju-on and Ringu.
