In a converted nuclear reactor, 70-year-old Dunia, the dying founder of a hi-tech orchard, passes on instructions to her younger successor Alia. The aim is to cultivate a replica ecosystem and replant the soil above. As preparations for resurfacing are underway, the intimate dialogue between the two scientists reveals stories of the past, the environmental disaster as well as their personal and collective loss. Alia is born underground as part of a cloning program, an entire generation reborn from the remnants of those lost in the apocalypse. She struggles with her memories, recalling situations and scenes from life above ground, although she has never experienced it. As Dunia’s stories from the world before the apocalypse become eerily familiar, Alia becomes intrigued by an early DNA memory encoding program. She starts questioning her origins, forcing Dunia to reveal it to her.
