 Stanley Wright uses an old-fashioned safe-cracking method that leaves very little evidence. As an ex-con and a recent arrival to the area, he becomes a strong suspect in a series of safe-crackings and the Highway Patrol puts a tail on him. Wright remains highly confident that he can outsmart his pursuers and devises an elaborate plan to crack a jewelry store s safe by slipping the tail while apparently attending a church service. The logistics of his scheme work as planned, but he is unaware that Dan Mathews has requested area merchants to sprinkle the contents of their safes with a powder that can be detected with a special light.
