Frieda , a therapist, is cheated by her husband Daniel. He makes love with Dorothea. Dorothea is wedded to Philip. Philip has an affair with his scholar Maggie. Maggie is in love to the florist Michael. Michael is married with Barbara. Barbara has a lover, her boss Marko. Marko is engaged with Simone Stern, a singer. Simone loves Leon. All of these secret liaisons could be undiscovered, if Simone Stern wouldn't be anxious to suffer from Aids. Without waiting for the test results, she informs her fiancé Marco about her apprehension of being Positive. Within a few hours the fear of being infected by the disease circulates in this group of people. Lies get transparent, secrets are uncovered, relations break up, Philip even has to pay his flam on his wife with his live.

It seems to be an intermediate world of peace and quiet, the garden and country house where four people look back on testing lives. And forward, to the time they have left. On the one hand, there is regret – on the other, satisfaction. In a way, they are looking forward to the future – but at the same time, a longing for death regularly arises. And who is actually behind the camera? Are we watching actors or real people? Is there really any difference? Garten is full of contradictions – it is not until the credits roll that we realise who these people from very different backgrounds are.
