The film shows the Högdal, Granholm mounds and the Ullna tip and includes interviews with people who in various ways relate to these sites. Karin Melinder, PhD in Social Medicine, describes the Högdal mounds as forgotten landscape sculptures and a silent cultural heritage. Anders Sandberg, retired Parks Superintendant, gives an insight into the work behind the construction of the mounds. Roland Kahlson, development manager for the Ullna tip, talks about how one works with such tips today and how they can be developed in the future.
