Asian adoptee Audrey Sullivan lives with white parents, Joe and Mary Sullivan, in White Hills,
Washington, along with her childhood best friend, Lolo Chen, who is also Asian but with biological parents. Audrey is an overachiever who works as a lawyer for a prestigious firm, while Lolo struggles to make ends meet with her
sex-positive art. Promised a promotion to
partner if she can close a deal with a Chinese businessman, Audrey and Lolo fly to China, joined by Lolo's cousin Vanessa, nicknamed "Deadeye", who is socially awkward and obsessed with
K-pop. In
Beijing, Audrey meets with her college roommate and close friend Kat, who is an actress on a popular daytime show, and despite being sexually promiscuous in college, is engaged to her co-star and Christian fiancé Clarence, who is saving himself for marriage. The group meet Chao, the Chinese businessman, at a party. He insists that for him to do business with Audrey, he must know about her birth family, whom she has never met. Lolo lies to him that Audrey is in close contact with them. Prior to the trip, Lolo had called Audrey's adoption agency and tracked them down. Audrey resolves to meet her birth mother and take her to Chao's party to close the deal. The quartet board a train to the agency, where they unknowingly share a compartment with a drug dealer. They are forced to consume copious amounts of cocaine before a train inspection; the drug dealer then steals their luggage and they get kicked off the train. Stranded in the middle of rural China, Lolo contacts former
NBA star
Baron Davis, whose team is currently playing in China. The four injure some of the players in sex- and dance-related accidents the following night, causing the team to refuse to drive them to their destination. The group hitchhike their way to the agency. There, Audrey discovers that her mother is not Chinese but rather Korean. In a last-ditch effort to secure the deal, one of Deadeye's online friends secures them a private jet to
Seoul, but without their passports, they pretend to be a new
Korean idol group to pass the border. Lolo livestreams their idol performance of "
WAP" on Instagram Live to prove their legitimacy, only for Kat's skirt to accidentally fall off, revealing a large devil tattoo in her pubic area. They are forced to instead take a boat into mainland Korea. Lolo's livestream inadvertently goes viral, with hundreds of millions of people seeing Kat's tattoo. Chao calls Audrey to inform her that the deal is off; she then is fired from her job, while Kat is at risk of losing her television deal and Clarence. The quartet have a falling out and split. Audrey learns that her birth mother has died, so visits her grave. There she meets her birth mother's husband Dae Han. He shows her a video recorded by her birth mother before her death, then reveals her friends had told him he might find Audrey at the grave. Meanwhile, Kat reconciles with Clarence. Lolo moves out of Audrey's house, Audrey returns to
Seattle and makes peace with Lolo and Deadeye. One year later, Audrey, Lolo, Kat, and Deadeye are in
Paris for a best-friends trip. Audrey has started her own law firm, Lolo has begun waiting tables and selling her art, Deadeye has accepted themself as
non-binary, while Kat's acting career has recovered and she is planning her wedding to Clarence. ==Cast==
