Xiaodong, a ride-hailing driver from the countryside, was swept years ago into a dream of cinema while working as a security guard at the Beijing Film Academy, and briefly shone as the inspiring 'security guard brother'.

Lucky and unlucky at once, their meeting is like an ordinary stone dropped into still water: it raises a violent splash, then ripple after ripple of consequences.
