Old Bai runs Chang'an Supermarket, the only shop of its kind in his neighborhood, until the chain store Wow sets up shop nearby and threatens to bury him. At 35, with his wife Yanzi at his side, he rallies neighbors and friends to keep the business alive and hold their own against a much bigger competitor. Expect scrappy schemes, community loyalty, and small-scale hustling as ordinary people try to outmaneuver a corporate rival on their own turf.
