In 1983 a sleepy fishing village in West Wales became the unlikely setting for an audacious drug smuggling plot worth millions of pounds. A gang of international drug runners planned to traffic tonnes of cannabis via the remote Pembrokeshire coastline. But the smugglers overlooked the inquisitive locals and dogged rural detectives who hunt them down.

What begins as a rural investigation eventually leads the local police on an international adventure involving speed boats, supercars with hidden panels, mansions with buried treasure and a cast of eccentric characters. Told by the people who were there, this is the story of how a small Welsh community and a local police force came together to take on an international drugs ring.

In this fifth episode, the Welsh detectives are in a race against time to track down the last member of the smuggling gang before the court case begins.
