Mrs. Pospisil (Berta Kammer) manages well on her own despite her 80 years. At least that's what she insists to her worried son Patrick (Philipp Hochmair), who has long wanted to send her to an old people's home. But one day, Mrs. Pospisil discovers a crack in the wall of her old apartment. She fills it up, but it keeps breaking open. The more energetically she tackles it, the more something sinister seems to spread from it. Is Mrs. Pospisil possibly no longer alone in her home? She would never ask her son for help; after all, she doesn't want to confirm his fears. The annoying janitor (Eva Maria Marold) also seems to be watching her constantly, just to be able to tell Patrick about a misstep. So Mrs. Pospisil will have to prove her independence one more time. And if it's the last thing she has to do - she has no intention of backing down .—Paul Ertl
