Due to alleged West contacts Bettina is arrested in 1984. Jan is a Stasi officer and expert in interrogation. For half a year, the officer and the dissident sit face to face almost daily, and the unbelievable happens: they fall in love with each other. In a few words and gestures and by means of a numerical code, they communicate. '11 means 'you are beautiful', '12 means 'I love you'. Jan and Bettina are always at risk of their love being discovered.
