Charles Boyer plays a man who has been blind since birth. His family obviously is well off and his brother doesn't want to spare any expense to cure him. However, Boyer's character is fatalistic and wishes everyone would just accept that he'll always be blind. And, when a doctor arrives who now says he MIGHT be able to cure him, the blind man assumes he's a charlatan and refuses the treatment. But, when his fiancée gives him an ultimatum, he reluctantly agrees--even though the odds of it being successful are low.
The story works reasonably well and the twist at the end is worth seeing. It's not an especially strong show so that I would advise you to download it quickly from archive.org, but if you are into 1950s TV DRAMAS, it is worth your time--mostly because Boyer is quite good (as usual).
