The Rig plot
The crew of the Kinloch Bravo oil rig, located off the Scottish coast in the dangerous waters of the North Sea, must be picked up and returned to the mainland. Then a mysterious, dense fog sets in. The oil rig is hit by massive earthquakes, and they are cut off from all communication with the outside world. As the crew tries to discover where this unknown force comes from, a major accident forces them to question who they can trust.
