Blond shrunken and black-haired big-headed eggs are a pair of best friends during adolescence, they think that everything can only be classified into two categories, either cool or lame! This pair of hormone-secreting babies are not stupid, but they are smart and useless. All they can think about is how to get rid of their virginity. They can describe everything as "sexual" and stunning. The reason for this film is that the TV set given to the big head was stolen. They were eager to go to heaven and sea to look around. Finally, they came to a broken hotel and met an old man named Mandy. Mandy said that he was willing to pay 10,000 yuan to hire them to go to Los Angeles to "do" his wife. The lecherous wretch and the big-headed egg were overjoyed, but they didn't know that this was "not the other"! So they happily boarded a plane to Los Angeles and launched their maiden flight (their first flight). But when it came to Los Angeles, things didn't go as they thought. In order to catch up with Mandy's ex-wife, the punk and the big head were always dealing with two federal investigators and a group of old people.
