"A man on the run - a man with no memory - a man with a secret. Time running out. Only a few days left for him to remember what he has to do to save the world. Who is Mr. Lutterworth? He doesn't know. What is his secret? He cannot remember. Yet a major oil company is ready to pay him a million, or kill him, for it. Foreign agents would stop at nothing for its possession..."
