What can you say about a tugboat that gets caught right in the confrontation between a tidal wave and a hurricane? What goes up must come down? Well, this one, the Haida Noble, comes down intact. She's a Canadian vessel that's commanded by one Christy Westholme who not only keeps her afloat but guides her to a crippled Russian spy ship that's well within the twelve mile limit. The spy ship has, in the meantime, knocked off a British-American rig without provocation. Christy wants to tow them in. . . they want to be towed out, beyond the twelfth mile. The Russians capture the tug and now, having survived wind and tide, we're in an International Crisis. All in all, a test of endurance.
