Cinch Knot

Pipeline Security Guard, Dan Webster, and a pump station technician, Gwen Stevens, discover a hidden nuclear device inside an ultrasonic pipeline inspection "pig," and are convinced it is part of a sinister conspiracy. During their investigation they uncover a multinational plot among influential oil and shipping leaders planning on disrupting the flow of Alaskan oil in the pipeline to drive the price of oil skyward. The fate of the Alaska pipeline, pristine Prince William Sound, the town of Valdez, thousands of innocent people, and global economic stability are threatened, unless the device can be disarmed and the schemers exposed.
