Summer Solstice is a collection of love stories about, and for, people of all different ages and generations. Each character's tale connects, weaving in and out of the others, mirroring and countering them so that, as the long hot summer draws to its close, each is forced to examine their lives and decide to whom their loyalties lie or else risk loosing everything they hold so dear.

Many years ago Thaddeus Hartington quarreled with his son David. Now he is seriously ill, but only wants to undergo a risky heart surgery, if he had the opportunity to reconcile with David. His dedicated doctor Kate sets out to find the missing person. She finds him in a small south English town, where he lives with his son Jeffrey. With charm and openness, Kate manages to win David's trust and eventually his heart. However, when he learns that Kate is on his father's behalf, this puts the young love to the test.

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...
