One day, alien aliens unexpectedly descended on the earth. Earthling Cheng Dawei was accidentally involved and became the temporary head of the "Alien Friendship Exchange Society" and organized an exchange and mutual aid group between Earthlings and aliens. In the process, various alien misunderstandings are hilarious and cultural conflicts continue, but the world is slowly changing because of these strange things. Three kinds of aliens and two earth partners "forced" to live together, team up, make trouble, and grow together, from playing tricks on each other to working together to save the day. On the basis of mutual understanding and trust between the two parties, an upcoming interstellar crisis was prevented. In the end, everyone recognized themselves, and the earth and the aliens realized transformation and integration amidst the laughter and curses.
