Lonlon, a panda prince born into royalty, inhabits a forest realm governed by his mother, the Queen. This domain includes diverse inhabitants such as a polar bear. To prove his worthiness as heir, Lonlon undertakes a royal test by attempting to climb a waterfall. His failure leads the Queen to declare him unworthy of his princely status, resulting in his expulsion from the forest. Forced into solitary exile, he embarks on a journey.

During this exile, Lonlon encounters numerous dangers, battling hostile adversaries along his path. His journey takes a pivotal turn when he is captured. Compelled to work in a circus under a ringmaster's direction, he performs alongside other animals, marking a stark contrast to his former privileged existence.

Beyond personal survival, Lonlon's experiences outside the forest involve confronting threats to his homeland. Evil bears conspire to overthrow the Queen and seize control of his ancestral territory, adding complexity to his struggles in exile.
