On the outskirts of the southern suburbs of Sydney, a satanic cult is performing sadistic rituals that had been discovered in an ancient grimoire. In the ritual, eleven women must be kidnapped and sacrificed on specific days after the summer solstice. After each sacrifice, the woman's naked body must be laid in sight of a religious place of worship, casting a curse on each denomination targeted. The leader of the cult, known as the High Priestess, believes in her deranged mind that the sacrifices will bring Satan and his army into our world.
The cult has purchased a property outside of Barton Park, where a large shed has been erected to hold the cult's congregations. A house has been converted to accommodate the abducted women who must be humiliated and degraded before one is sacrificed every two days before the year's first full moon. The women are chained to the floor, with little to no chance of escape from the well-guarded house of hell.
A task force is set up in the suburb of Southern Palms to catch the killers. The team, led by Detective Tank Dodge, consists of detectives, a forensic pathologist, an investigator, a profiler, and a computer analyst. Unknown to the team is that they have moles in their ranks who keep the satanic cult informed of any impending threat. As the body count starts to rise, Tank and his team need to discover the whereabouts of the cult and the kidnappers who are abducting the young women.
