When Germany is hit by a drought, the Ruhr area is threatened with the collapse of drinking water. Meteorologist Martina Fechner is appointed head of the crisis team, but has to recognize that her colleagues see the crisis as an opportunity for their own career. When even highly toxic germs are discovered in a reservoir, the region is also threatened by a plague.
Unfortunately the movie Heat Wave is not yet available on HBO Max.
