A Los Angeles PD detective and a US Customs Inspector are on the trail of a drug smuggler they know is planning to smuggle a large amount of pure heroin through the L.A. waterfront. They have already caught one of the smuggler's couriers, but he's too scared to rat out his boss, a man named Thatcher. The cops get a lead that a boat will be coming into L.A. harbor with Thatcher aboard, but they don't know what he looks like. When the plan to catch Thatcher goes awry, the chase is on.
