In the 1990s, Zhou Weidong, a live-in son-in-law, discovers that his daughter is being mistreated and resolutely leaves with her. Starting with a small stall selling crispy fried-pork pastries outside a factory gate, he establishes himself through his craftsmanship and honesty. Facing harassment from his ex-wife's family, workplace discrimination, and a custody battle, he remains calm and resolves each problem with account books, licenses, and legal paperwork. His little shop opens, a catering contract is secured, and his daughter gradually transforms from timid to confident. In the end, custody is rightfully restored, and father and daughter embark on a new life built on stability and hard work.
