This is a world ruled by ratings. As long as they are legal citizens, everyone has a special chip implanted in their eyes to view the real-time ratings of people within their field of vision. Mobile phones are equipped with a rating system, allowing users to give one- to five-star evaluations for anything related to others. From sharing friends’ photos to greeting strangers, everything can be rated. These scores collectively form each person’s overall rating—those above 4 points are respected, above 3 are ordinary, above 2 are despised, and those barely above 1 struggle to get by.
There is a special tier within this rating system: those above 4.5 are called "Big Fours," a symbol of glory that comes with many privileges. Lacey currently has a rating of 4.2. To maintain and improve her score, she spends a lot of time giving five-star ratings to both acquaintances and strangers. Every morning, she practices smiling and laughing in front of the mirror to leave a good impression on others. Despite almost always insincerely flattering everyone she meets, her rating never seems to rise, hovering around 4.2.
The lease on her apartment is about to expire, and the landlord has no intention of renewing it. Lacey and her brother Ryan, who has a rating in the 3s, must find a new place to live. Ryan can share an apartment with classmates, but Lacey wants to move to an upscale community. She has her eye on an apartment, but the rent exceeds her budget. Just as she hesitates, the real estate company offers a discount—20% off for Big Fours. Lacey is tempted, but how can she quickly raise her rating to 4.5? She consults an expert and receives this advice: expand her social circle and strive to get more five-star ratings from Big Fours.
Lacey’s daily life is a simple routine—she mostly interacts with passersby, waitstaff, and colleagues. Where can she find so many Big Fours? Just as she worries, an old classmate she hasn’t seen in years, Naomi, visits her social media page. The 4.8 rating beside Naomi’s name stuns Lacey. Naomi comes from a wealthy family, has a mean personality, and often bullied Lacey in the past—even stealing her boyfriend. But Naomi’s social circle is full of high-rated individuals, which makes Lacey envious. To earn a five-star rating from Naomi, Lacey takes a photo of a ragged cloth doll on her desk and posts it online. This doll was a gift from Naomi years ago, mocking Lacey for being a pushover. The photo actually catches Naomi’s attention, and she gives Lacey a five-star rating.
But that’s not the end of it. That evening, Naomi unexpectedly reaches out to Lacey. After a bunch of meaningless pleasantries, she reveals her real intention: Naomi is about to get married and wants Lacey, as an old classmate, to be her bridesmaid and give a speech at the wedding. The guests are all celebrities with ratings above 4.5. If Lacey can win their favor, reaching 4.5 will be effortless. So Lacey happily agrees and even prepares a tear-jerking speech for the wedding.
The wedding is held on a private island, and Lacey must fly to the harbor in advance to attend the rehearsal. Right before departure, she argues with her brother Ryan. Ryan thinks it’s hypocritical for his sister to cater to an unfriendly "friend" like Naomi, and the siblings angrily give each other one-star ratings. Fuming, Lacey storms out of the house and bumps into a highly-rated person. Her apologies are ignored, and her rating drops from 4.2 to 4.1. This triggers a series of nightmares.
At the airport, Lacey’s flight is canceled, and the only available seats on another flight are reserved for those with ratings above 4.2. Lacey yells in frustration, attracting airport security, who penalize her by temporarily deducting one point for 24 hours. During this period, all low ratings count double. Unable to fly, Lacey decides to rent a car. After waiting in a long line at the low-rated counter, she ends up with an outdated car due to her low score. When the battery dies, she realizes current charging stations aren’t compatible with the old model. Hitchhiking on the road only earns her more low ratings. Meanwhile, Naomi repeatedly calls, angry that Lacey missed the rehearsal.
Exhausted, Lacey drags her suitcase along the highway until a truck stops beside her. She looks up and is startled—the driver’s rating is 1.4. With no other choice, she gets in. The driver is Susan, nearly fifty years old. From their conversation, Lacey learns that Susan was once highly rated. Years ago, Susan’s husband was diagnosed with terminal pancreatic cancer. A promising treatment was given to another patient with a higher rating instead. After her husband’s death, Susan saw through the hypocrisy of the rating system and started speaking her mind freely, offending many people and causing her rating to plummet. But now Susan lives happily, free from doing things she dislikes just for ratings.
After sleeping for a few hours in the truck, Lacey parts ways with Susan when they are only an hour away from the harbor. Susan leaves a bottle of wine in Lacey’s suitcase to keep her spirits up. This is the first time in Lacey’s life that someone has selflessly helped her without caring about ratings.
To hitch another ride, Lacey pretends to be a fan attending a comic convention and gets into an RV headed to the harbor. While struggling to chat about a sci-fi series she’s never watched, Naomi calls. Naomi forbids Lacey from attending the wedding—Lacey’s rating has dropped to 2.6, and Naomi is embarrassed. She only invited Lacey because experts suggested that associating with lower-rated people could help improve her own score. Given the situation, Lacey can no longer be a bridesmaid.
Feeling deceived and furious, Lacey vents her anger by yelling at the cosplaying fans that she’s never watched their "stupid show." Her outburst gets her kicked out of the RV and showered with low ratings. Undeterred, Lacey drinks the wine Susan gave her, "borrows" a motorcycle from the roadside, and races toward the wedding venue with her suitcase. After countless hardships, she finally arrives at the wedding.
Covered in mud and looking disheveled, Lacey doesn’t care. She changes into a pink bridesmaid dress and rushes into the wedding hall. This is her last chance, but her conflicting feelings—wanting to please Naomi while hating her—make her speech illogical, alternating between praise and insults. She disrupts the entire wedding, and her rating plummets to zero.
At the police station, the chip is removed from Lacey’s eye. Sitting on the cell bed, she feels a mix of emotions. Spotting a well-dressed man in the opposite cell, she finds him increasingly irritating and starts shouting insults across the hallway. Lacey never expected herself to say such things, but the two exchange unrestrained curses and burst into laughter. It feels surprisingly liberating to speak one’s mind.
