The strongest tsunami in the history of mankind led to the reconstruction of the world. On one of the surviving patches of land, there are almost no stocks of wheat seeds left, and the surviving people from other islands, it seems, do not intend to share. In order to transport grains from another landmass, a team of engineers manages to create an aircraft that is difficult to detect, but sends it on its first flight with a bug. Will their invention succeed in covering a distance of several kilometers over water and returning bread to people, or will an unresolved error prove fatal to the project?
