During World War II, American sergeant Larry Nevins is blinded by a German sniper while fighting in North Africa. He is taken to a Pennsylvania hospital for other blinded soldiers, where he struggles to accept and come to terms with his disability.
Though initially despondent, Larry is taught to orient himself and walk through the grounds and in town by memorization and with use of a cane. He befriends Joe Morgan, another blinded veteran, and Judy, a local bank teller who volunteers by socializing with disabled soldiers.
One day, Larry, unaware that Joe is black, utters a racial slur, causing a rift between Larry and the others. Meanwhile, he progresses well in his recovery, passing a crucial test to see how well he can handle himself on the street. He is cleared for furlough, so Judy takes him to spend a weekend at her sister's nearby cabin, where he goes fishing and is entertained by her family.
From Judy's brother-in-law, Larry learns of a very successful blind lawyer, giving him hope for the future. After dinner, Judy reveals her love for him. Larry tells her that he needs more security and family support and already has a fiancée in his Florida hometown. Somewhat dispirited, he goes home and has a rough time dealing with the racial attitudes of his Southern parents and friends. His fiancée's family is having doubts about his fitness as a son-in-law, and his parents are downcast because of his disability.
Larry is happy to see his fiancée Chris, though he still thinks of Judy. After a bad experience at his homecoming party, he tells Chris the difficulties that they can expect with his disability, and that he wants to relocate rather than be patronized with the menial local job that her successful father has offered him. After some thought, Chris tells Larry that she does not feel strong enough to marry and move far away with him while he struggles to make a new life for both of them.
Returning to the hospital, Larry takes a side trip to Philadelphia and meets the successful blind lawyer played by Frank Wilcox. The lawyer tells him that life is difficult but worth it and that his wife was an invaluable helper to him in his career.
At the train station en route to begin a more advanced rehabilitation course, Larry is unexpectedly reunited with Judy. They joyfully declare their love.
Boarding the train, he hears Joe Morgan's name called. He catches Joe's arm, apologizes for all the hurt he has caused and asks if they can be friends; Joe accepts the apology. They board and sit together as the train pulls out of the station.
