Lyn's husband, Peter, went blind in an accident two years ago. To help adjust to being sightless, they played games where Peter identified objects through guesswork or memory. To Peter, blindness eventually becomes a sort of blessing, as he learns to become sensitive to everything around him, constantly winning the games he starts pushing Lyn to play.
Peter's condescension and almost omniscient knowledge begins to frustrate Lyn until she realises she is like a slave to Peter. One day, at Peter's insistence (so he can guess what she's chosen to do), they go on a drive. Lyn offers Peter a new test: turning left or right, when she's driving right next to a cliff. Peter chooses right, and they drive off the cliff.
