The engineer Rosalie leads a life without standing still. She doesn't feel old for a long time, only mature. When Rosalie returns to Germany after a fainting spell at a solar project in Africa, it's just supposed to be a breather. When she shows up at her bourgeois sister Margret's with a huge container, she is not very enthusiastic about the surprise visit. The retired teacher sees right through that Rosalie isn't staying with her voluntarily. The well-travelled woman is broke!

On the other side of the wall there is the room of the highly talented high school graduate Karla, who rents a part of Margret's house with her father Harald. After a failed first meeting, Rosalie befriends with the wheelchair-bound teenager and sets her mind on getting Karla out of her sheltered isolation, even against her will.
