In 2064 the post climate change world is on the verge of destruction. The UN has developed a form of time travel: a person's memories and their personality along with them can be transmitted to the past, to the person themselves in the moment of birth. Henrik, a brilliant but narcissistic physicist, has been chosen for a mission to publish the blueprint of the fusion reactor - based on his invention - to the entire world and thus prevent climate change from ever happening. But something goes wrong: Henrik is born in the wrong body and must learn humility while living his new life.
