Drawing heavily from Arkady and Boris Strugatsky's 1971 novella 'Piknik na obochine' ('Roadside Picnic') as well as Andrei Tarkovsky's 1979 film adaptation ('Stalker'), 'Tretya planeta' tells the story of a father seeking a cure for his ill daughter by venturing into an area known only as "The Zone" to request help from the mysterious healers that dwell within its forbidden borders.
