CANNABIS COVE: OPERATION SEAL BAY

BBC One Wales and iPlayer

4th and 11th December at 9pm

In 1983 a sleepy Pembrokeshire fishing town became the unlikely setting for an audacious international cannabis smuggling plot worth millions. 

The story begins when the local farmers and fisherman of Newport make a series of strange discoveries. Oddly dressed men traipsing over private clifftop farmland, expensive marine equipment found at a cove only accessible by boat, and a hatch hidden in the shingle of another remote beach, which leads to a strange underground chamber.

Who built it? And why?
