A pig invents the internet before electricity exists and nobody in the movie questions it for a second. McDull watches this unfold with the same blank stare he'd give a grocery list. The joke isn't that it's absurd, the joke is that absurdity is just how the world works, and McDull is too tired to care.
An archaeologist's discovery of a bizarre ancient artifact sets off an unexpected chain of events. The object belongs to Mak-zi, a long-dead Chinese philosopher whose inventions were centuries too clever for their own good. Nobody wants the crude relic, so it drifts endlessly down the Yangtze River on a barge, unwanted and forgotten. Fast forward eighteen generations. McDull is a kindergartener living a completely ordinary life, blissfully unaware that he's the direct descendant of a genius visionary. When the artifact resurfaces, McDull gets pulled into a whimsical adventure that connects him to his ancestor's legacy. What follows is pure comedic chaos as this dopey kid stumbles through situations that require actual intelligence, all while armed with nothing but his good heart and relentless optimism. The film blends absurdist humor with Chinese cultural history, mixing ancient philosophy with modern childhood confusion. Parents and kids alike will find something to laugh at here, whether it's McDull's bumbling antics or the ridiculous situations his ancestor created generations ago.
