Our detectives are on the trail of some killer armed robbers and a missing truckload of gold. The Armed Robbery Squad's Detective Calabrese returns with Simon squarely in his sights, and Stanley and Jarvis face the ultimate betrayal.

These hijackers are seriously big-time criminals. Cold. Focussed. Ruthless. The trigger-happy troops from Armed Robbery relish the opportunity to return fire, only their targets seem trained on Homicide. Old wounds feed the feud until even the senior officers are squaring off.

For Simon especially, this case has him rattled. Hard to keep your cool when you're staring down the barrel. Hard to believe the body count keeps rising. Suspicions are raised ? is there a rat in the ranks? It's unthinkable, but there's a reason why they call it gold fever. One nugget is enough to come between the oldest allies. What price a truckload?
