A Darker Shadow Bonanza : Season 11 Episode 10

Joe's friend Wade Turner, a storekeeper who is engaged and has been offered a promotion at work, tries to deal with a devastating brain tumor that leaves him with a paralyzing sensitivity to bright light and will soon render him blind. Turner lets his pride get in the way and decides to put off both his marriage and a surgery that could save his sight, but his attitude could be far more costly when a co-worker tries to rob him in a remote area.
