Sun, an autistic man obsessed with finding a means of ending his life but who never succeeds in carrying it out, has to put his plans of suicide on hold once again when Uncle Mok, the owner of a coffee shop and little library called Tiny Butterfly, dies suddenly in the street right before his eyes. He isn't alone, though. Yaimai, a financial planner who likes one-night stands, and Tor, a sixteen-year-old runaway, also happened to bear witness. Together, the three strangers give their account to the police and arrange the kinless man's funeral.
