The present imperial court seeks out Foreigners, assigning them with various positions according to their individual talents in hopes of changing the current archaic civilization into a better one. An influential dissident, Zuo Yunqi, sneaks into the imperial court pretending to be a Foreigner in order to save his father but is exposed by the Landlord, who is an expert in distinguishing aliens. Their meeting sparks off a series of mental and physical battles that are sometimes comedic, but they ultimately come to a consensus to cooperate. While they successfully prevent a conspiracy, they find out about another Foreigner who has secretly set up an alliance to overthrow the current power and build a new, free-for-all society. Zuo Yunqi and his gang are forced into taking action.
