The series takes place in 1997 in Wrocław, when the 1997 Central European flood is nearing the city. The main character is the hydrologist Jaśmina Tremer, who returns to Wrocław after many years to help handle the crisis. During the series, the characters have to face not only the incompetence of the local authorities, but also their own past.[3]
Apart from Wrocław, the names of the towns and villages are fictitious, e.g. Kęty is actually Łany, while Gierżoniów is Nysa, situated on Nyskie Lake, where the regatta was actually held at the time, which delayed the emptying of the reservoir located on the Eastern Neisse, which is a tributary of the Oder on which Wrocław lies.
