17-year-old Mae has decided that life is meaningless after her mother passed away. When she moves to California with her single father, her friends give her a summer bucket list. Afraid to start her senior year completely alone, Mae decides to complete the list, hoping for it to bring her out of her shell. When Mae meets someone willing to help her complete the bucket list, it leads to a pretentious friendship. They become closer, as they find that both of them share the same belief that life is ultimately meaningless. Until she realizes that he seems to have a different perspective on it. While Mae is somewhat reluctant about what he tries to show her about life, she can't help but have it start to rub off on her. Mae realizes that while his absurdist views on life were slowly impacting her, her nihilistic, hopeless view on life was also influencing him. Will their relationship turn out to be as doomed as their beliefs?
