A man and his wife, Helen, attend a rom-com—her favorite—only to find the film interrupted by the couple seated in front of them. The woman insists upon narrating everything in the film to her husband, a grievous annoyance to the man seated behind them, until he realizes the woman's husband is blind. Throughout the film, he and Helen are amused by the commentary, only to be horrified when it takes a dark turn.
In the film's final moments, as the on-screen couple at last unites in love, the wife changes her narration and describes heartbreak, scorn, and disillusionment. The blind husband begins to cry. Horrified by these unfolding events, Helen and the man are both quiet and shaken as they leave the theater. In the hall, the man recognizes the blind husband and tells him the true ending. The blind man sarcastically thanks him.
Only a few weeks later, Helen gets diagnosed with bladder cancer, and takes her husband on a final trip before she dies. In a hospital bed in her final moments, Helen tells him when she used the restroom in the movie theater that day, she heard the raspy whisper of the wife seated in front of them. Through the stall door, the wife told Helen she would die. Helen passes away the day after describing this instance, and the man realizes no ending can be happy when grief clouds the watcher.
