When their son Esben moves away from home, middle-aged Danish couple, Kjeld and Vibeke, become uncertain of their own path of existence; his absence leaving them with a feeling of needlessness. Attempting to revive the magic sparks of their younger days, they move into their old student apartment where they first fell in love. Recapturing their youth is literally changing them in strange and unexpected ways. And as they wake up one morning to find that they are actually now thirty years younger, they are forced to realise, that the past they once knew might no longer exist.
