Story without spoilers

Phát and Diệp want to bring up Phú Quý according to their own ideas, so they construct a deliberately confusing world around him. In this household, wealth and poverty—and truth and deception—are not always what they seem.

As Phú Quý matures, he starts making choices independently. Those choices lead to a series of humorous mishaps that gradually bring long-buried secrets into view. Without revealing the film’s developments, the story focuses on a family forced to confront the distance between parental intentions and a child’s need to make his own way.

What to expect

The film combines family and comedy, using an unusual upbringing as the source of its central misunderstandings. Its premise points to humor driven by family mishaps and conflicting expectations, while the broader story addresses family bonds, generational differences and the importance of parents and children listening to one another.

The runtime is 1 hour and 58 minutes, giving the film room to balance its comic setup with its more heartfelt family concerns. The supplied synopsis presents it as a relationship-focused comedy rather than a story centered on action or suspense.
