How would you live your life if you got a second chance? The brilliant young physicist Henrik and his fellow students develop a fusion reactor that produces endless clean energy, potentially saving Earth from environmental catastrophe. The reactor, however, is harnessed for commercial use, and the consequences for the planet and society are devastating. By the year 2064, the world is ravaged by climate change. The UN manages to develop a form of time travel that allows a person’s memories and personality to be sent back to the moment of their birth. Henrik is sent back to the past with the goal of preventing the catastrophe from escalating before it’s too late. Something goes wrong, though, and Henrik is forced to begin his mission from a very different starting point than he’s used to. Thus begins a race against time-and against himself. After Us, the Flood is a drama, spiced with sci-fi elements, that explores relationships, identity, greed, and the reasons why humans haven’t yet been able to stop climate change.
