In the eyes of aliens, earthlings are just entertainment for them to play. A group of aliens made a bet, the stakes are the survival of the earth. They randomly selected a person on the earth and gave him the superpower to make his wishes come true. If this person eventually becomes an insatiable evil person, the aliens will choose to destroy the earth, but if this person still maintains his kind nature, it means that the earth still has the meaning of continuing to operate. Neil (Simon Pegg), an ordinary and introverted middle school teacher, became the chosen one who is related to the survival of the earth. After possessing superpowers, a series of accidents happened around Neil that made people wonder whether to laugh or be afraid. At the same time, Catherine (Kate Beckinsale), the woman Neil secretly loves, is also involved in danger.
