For the US Government it's a losing battle. The smugglers no longer shy from confrontation, they relish it – blowing Coast Guard jets out of the sky and sinking their cutters with powerful bazookas. They've become a co-ordinated force of devastating ruthlessness.

The US anti-drug agents are a squabbling shambles. A radical solution is needed. And Rear Admiral Ian Hardcastle is just that. He will lead an élite and fearless unit armed with the latest equipment and deadliest weaponry. Their sole aim is to hit the smugglers. And hit them hard. They are known affectionately in the business as Hammerheads.
