In Rozwarowo, a village in northern Poland, thatcher Alfred Smolczynski has spent decades renaturalizing a drained moor, work he began in the 1980s against local resistance. The film follows the next phase of that project: bird conservationists reintroducing the sedge warbler, a species that depends on healthy wetland habitat. Ornithologist Krzysztof Kałużny and his colleagues move into the village for about a month, catching insects in the surrounding fields and hand-feeding chicks every half hour from sunrise to sunset. The birds progress from indoor cages to outdoor aviaries set up on Smolczynski's land before their eventual release into the wild. Interviews with the villagers show a community that has come around to seeing the restored moor as an asset rather than a nuisance, and the camera lingers on the practical, unglamorous labor of ecological restoration: cutting reeds, hauling equipment, watching for birds that may or may not return. It is a small, specific case study in what it takes to bring a degraded ecosystem back.
