In this ethereal twist-filled noir, a young man has a nightmare in which he kills a man. But after he wakes up, he's caught in a web of suspicion when evidence links him to a murder exactly like the one in his dream. Starring DeForest Kelley -- years before his breakout success as the irascible Bones in "Star Trek" -- this B-movie classic is based on the short story "Nightmare" by Cornell Woolrich, one of the pioneers of suspense writing.
