A kidnap, a theft, and a murderous moon-worshipping cult: Detective Sergeant Milburn has his work cut out to solve several cases that all appear at once. Milburn's job is trickier as both victims are friends with his girlfriend. He desperately needs to solve the cases but has to keep his personal involvement secret. With the clock ticking down on the fate of the second missing woman, the pressure ramps up.

Penfold, the detective's enigmatic surfer friend, is called on to help investigate. His puzzle-solving genius helps sift real clues from red herrings. The struggle for leads is constant, until it becomes clear that Penfold and Milburn are, in fact, central to all the crimes.
