Luther (Clint Eastwood) is a highly skilled thief. After a far-sighted plan, he sets his next target on the mansion of millionaire Walter Sullivan (E.G. Marshall). While the Sullivan couple were on vacation, Luther sneaked into the mansion. Just as he was confident and ready to do something, Luther saw Walter's wife Christie (Melora Hardin) in the one-way mirror in front of him and a man lingering figure. This man is none other than current President Allen (Gene Hackman). What Luther didn't expect was that the originally passionate love between men and women turned into a bloody murder in an instant. Luther watched helplessly as Allen killed Christie. At the same time, he also became the biggest suspect in this murder. In order to clear his name and expose Allen's ugly face, Luther decided to fight evil to the end.
