An average, everyday metalworker and volunteer firefighter content in his marriage to his childhood sweetheart finds his emotions unexpectedly stirred when he falls for a pretty waitress from a nearby town in director Valeska Grisebach's modest romantic drama. Marcus Koplin (Andreas Mueller) leads a happy yet uneventful life on the outskirts of Berlin. Though his union with longtime love Ella (Ilka Welz) is a happy one, the loving pair lead a quiet and somewhat passionless life of placid devotion. When Marcus happens across the scene of a tragic suicide, his attempts to put the incident out of his head prove considerably less effective than he initially thought. Later, when Marcus and his fellow firefighters travel to a neighboring town for a training session, a night of drinking and merriment leads the presumably devoted husband into the bed of pretty waitress Rose (Anett Dornbusch). Subsequently torn between his wife and the other woman, Marcus attempts to make sense of his impromptu extramarital affair while pondering the possibility that he may genuinely be in love two women at the same time.
