Oliver and the much older photographer Hendrik are a couple. A rather contrasting couple: Hendrik has already achieved a lot in his life and is considered an 'old hand' in his profession. Oliver, on the other hand, is only at the beginning of his career as a photographer and has retained a childlike naivety and playfulness in his life plans. Oliver and the young Silvia meet at a photo session. It is immediately clear to the ambitious Silvia that Oliver is her springboard to a modeling career. That same evening, Hendrik proposes to Oliver. But Oliver makes an almost unfulfillable condition: He wants a child! Hendrik is completely at a loss. What should he do? Then Silvia bursts into his house. All she really wants is to be photographed by Oliver. But things turn out differently...
