Elliot Richards, a socially insecure technical consultant working in a call center, has been in love with Allison Gardner for almost four years. One evening, which has already started out particularly badly for Elliot, she turns him down. Elliot wishes with all his heart that she was present in his life-and he is heard. An incredibly beautiful girl approaches Elliot and, posing as the Devil, Lucifer, Princess of Darkness, offers him a deal: seven wishes for him, his Soul for her. Elliot is quickly persuaded and agrees. But every wish granted also has huge negative consequences, and soon Elliot wants to terminate the contract. The only thing that matters to him now is the chance to try his luck on his own journey.
