Someone has developed the world's most powerful laser - so powerful, it causes volcanoes wherever it strikes. His first blast raises a cone in the Peoples' Republic of China, who naturally sends agents to investigate. His next blast targets the Soviet Union, and they dispatch their own people. Meanwhile, the IADC sends their own agent Diana Prince. The agents must join forces to discover who controls the laser. But when they discover the mastermind's surprising motive for creating volcanoes, they must decide whether stopping him is the right choice.
