In early 1980s Hong Kong, three unemployed friends—Ah Long, Hai Zi, and Zhu Zhu—launch a fish stall on Longzhu Street but soon see their booming business collapse under Hai Zi’s small-time profiteering and poor ethics. When they fall apart and drift into hardship, Ah Long finds a second chance under street-vendors’ leader Kui Mei, learns the true value of hard work and integrity, and reunites with Hai Zi and Zhu Zhu to merge their stalls into a principled partnership.
