A brilliant young physicist, Henrik, and his fellow students develop a fusion reactor that produces endless amounts of clean energy and could save the planet from environmental catastrophe. But the reactor is harnessed for commercial use, with disastrous consequences for the planet and society. In 2064, the world is ravaged by climate change. The UN succeeds in developing a form of time travel that can return a person's memories and personality to the moment of birth. Henrik is sent back to the past in an attempt to prevent the escalation of a catastrophe before it is too late. Something goes wrong and Henrik is forced to begin his mission from a very different starting point to the one he is used to.
