Plot summary
Dr. Yuri Soboda, a former professor at the University of San Francisco, has built a laser weapon and pointed it at the city, warning the authorities that San Francisco will be destroyed unless he is paid a large sum of money. Two teenagers who have slipped into an abandoned railway depot are nearby when a white van pulls up and a cannon pointed at a large clock fires around the area, then burns and melts. Inspector Ronn Warren of the San Francisco police force is the man in the middle of it, and the officer hunting the person behind the threat to the city.
