Danny Dako (Jack Gellenhall) is mentally ill, and one night he was summoned to sleepwalk, thus avoiding the bizarre accident that a plane crashed into the ceiling of his room. Since then, his life has changed, with frequent hallucinations. He often sees a rabbit, Frank, who tells him that the world will end in 28 days, 6 hours, 48 minutes and 12 seconds; he gets a book, the Upanishads on time Travel, and has a strong curiosity about the time travel and offline universe mentioned in the book. As the end of the world approaches, Jack's life becomes weirder and weirder, and his new girlfriend and family are also involved. It seems that Jack needs to pay more if he wants to realize his wish to save the world.
