Throughout the '70s and '80s, the Highland fishing village of Ullapool was a tough place to make a living. Renowned for its lawlessness, it was no place for the squeamish. In the summer of 1989, a local man named Chris Howarth met an expatriate Scot who offered him some work, and set in motion a chain of events that would lead to what would be the UK's largest ever drugs haul. Around the same time, working on a tip-off from a local informant and intelligence from their Spanish counterparts, Customs and Excise became aware of a major plot to smuggle huge amounts of drugs into the UK around Ullapool. As a result of this information, Operation Klondyke was born. The trail would lead from Ullapool and the east coast of Scotland to the Costa del Sol, Gibraltar, and Venezuela. It would uncover distribution channels from Colombia's notorious Cali cartel to Europe and North America, operated by ruthless Spanish smuggling outfits. White Gold tells the inside story of Operation Klondyke through the eyes of both the hunters and the hunted.
