Hey We've Got A Problem Here

Overview

Having found oil in Alaska, Mogul must find a way to move it, and Brian Stead is testing a submarine tanker designed to travel beneath the ice, using a former Royal Navy submarine off St. Lucia. Stead, Peter Thornton and Willy Izard arrive to see the trials completed, but the submarine, with Stead aboard, becomes stuck on the sea bed, leaving everything in the hands of Captain Simon Broadsword.
