A reclusive man fleeing past trauma rents an apartment in Melbourne from an eccentric German billionaire. As a serial killer known as The Melbourne Mutilator terrorizes the city, he begins to suspect his landlord is not only involved - but leading a secret satanic cult that has controlled Melbourne for decades.

After a homeless ex-filmmaker witnesses a kidnapping, he comes to believe that he is trapped in a horror movie filmed by the city's CCTV, where the only way to survive is to stay on camera - no matter what.
