Is it crazy to think that you can ›turn back‹ time? Peter Taler certainly thinks so when he first gets wind of what Knupp, the old man who lives opposite him, is planning. Because he wants to make the seemingly impossible, possible. The first thing Taler notices is that strange things are happening in the house opposite, where eighty-year-old Knupp lives. He starts to spy on him and record the goings-on with his camera, but by the time he realises he is being spied on too, he is already tangled up in the events on the other side of the street. Old Knupp, who lost his wife twenty years ago, is convinced that descending like Orpheus into the realm of the dead is not the only way to find your way back to a loved one. And he is not alone in his convictions, sharing this theory with famous minds such as Einstein and Aristoteles. But putting it into practise is not that easy. In fact, it is practically impossible. But this is where Taler comes in.
