Law Lik-ah (Kevin Cheng) used to practice law for personal fame and glory but after setting up a Legal Advice Centre with his cousin George Mai (Alex Lam) and his good friend Tin Ka-fu (Sam Lee) in Sham Shui Po, Lik-ah changes his mind and realizes that legal representation is not only a privilege of the rich. Soon, Lik-ah becomes the Peoples’ Hero of Sham Shui Po, helping grassroots groups fight against injustice with unconventional tactics.
