A pair of hit men have a very bad day, and the resulting bushfire draws attention to a meth lab and two burned bodies in a Mercedes. As Inspector Hal Challis of the Crime Investigation Unit struggles to link these events to major meth suppliers flooding the Peninsula with drugs, he also finds himself spending valuable time fending off jurisdictional challenges from Melbourne’s Major Drug Investigative Division. Meanwhile, Sgt. Ellen Destry, of CIU’s sex crimes unit, is hunting for a serial rapist who is extremely adept at not leaving clues.
