A group of escaped criminals hijacks a Russian fishing vessel "Udachlivy" ("Lucky") in the waters of North Pacific. A Soviet Border Guard patrol ship "Yuri Andropov" and US Coast Guard helicopter make a joint operation to release the vessel. What neither criminals, nor border guards know is that the fisherman is loaded with smuggled drugs, and the American drug lord goes on his fast boat to get the drugs from "Udachlivy".
