A Wave Standing Still (1970)

Lost in thought in the midsummer heat, Georg suddenly has only one goal. To make his huge, overgrown garden beautiful again at the weekend. But as he spends his days alone in the house he once shared with his ex-wife Sieglinde, who comes to visit at the end of the weekend, he has to deal not only with the garden, but also with absurd visits, memories, nosy neighbours and himself.
