As a free-spirited goose named [Peng](\/actor/jim-gaffigan) soars through the expansive skies of China, his carefree attitude comes into conflict with the strict leadership of [Bing](\/actor/diedrich-bader), leading him to inadvertently abandon his flock during a moment of rest. At the same time, two courageous ducklings, [Chi](\/actor/zendaya) and [Chao](\/actor/lance-lim), set off on a daring quest to the enchanting world of Pleasant Valley. However, their adventure quickly takes a wrong turn when a reckless move by Peng results in them becoming separated from their group.
In their race to evade the malicious cat [Banzou](\/actor/greg-proops), the ducklings encounter Peng, who remains blissfully unaware as he bravely faces off against their fearsome pursuer. This chance meeting forges an unexpected alliance as Peng's wild antics lead to an unfortunate injury—a broken wing after a mishap with a gong. Stranded, he now relies on Chi and Chao as makeshift protectors, solemnly vowing to reunite with his original flock.
Navigating through a myriad of misadventures, Peng manages to win the affection of the ducklings, who slowly begin to look past their initial fears. Yet, before he can lead them back home, Peng reunites with his own kind, forcing Chi and Chao to confront his true intentions. Each group now sets their sights firmly on their individual journeys. Despite feeling defeated, Peng makes one last attempt at flying, only to be grounded by [Carl](\/actor/carl-reiner), a wise hermit squirrel, who sympathetically crafts a rudimentary wing to help him.
Motivated by this generosity, Peng strives to find Chi and Chao again, yet their fate appears grim as Banzou re-emerges, capturing the ducklings. Showing remarkable courage, Peng confronts the sinister cat, but not without sustaining severe injuries during this fierce encounter. In a daring escape attempt, the ducklings ignite a rocket, propelling Peng into chaos.
Battered and exhausted, Peng remains committed to returning Chi and Chao to safety, but a sudden snowstorm exacerbates his already dire situation. However, the ingenious ducklings recall the honking technique Peng taught them, and they call for [Jingjing](\/actor/natasha-leggero), Peng’s girlfriend, who ultimately comes to their rescue from the biting cold. Bing, finally seeing the light, allows Chi and Chao to join the goose flock and welcomes Peng back with an embracing warmth.
In a touching moment, Peng shares his aspirations of starting a family with Jingjing, hinting at the possibility of future joys to come. Just as the credits begin to roll, an unsettling atmosphere looms. We catch a glimpse of [Larry](\/actor/craig-ferguson), the determined turtle who had tried desperately to warn Peng of impending doom. As Larry ventures towards the valley, he encounters a troubling silence. The once-vibrant landscape lies vacant and desolate, as if life itself has been extinguished, leaving behind an eerie stillness that raises more questions than answers.
