Abducted on Prom Night

At an off-campus college party, high school senior Kimber rejects an offer for a ride home from an attendee named Luke. Outside, she steps into an idling vehicle, asking, "Hi. For Kimber?" The driver immediately locks the doors and accelerates, ignoring her demands to "Stop the car!" latestnetflix.com's take is that Kimber forces the door open and rolls out of the moving vehicle to escape.

Two months later, Kimber remains under home lockdown imposed by her mother, high school principal Shawna McCann. Kimber visits the office of her father, Paul McCann, who asks her to enter the passcode to his private office safe: "I will take my chances with a good old-fashioned safe any day." At school, Kimber is caught with test answers written on her arm and sent to the principal's office. Confronted by Shawna over her slipping academic record, Kimber attributes the household tension to her parents' divorce, asking, "Are you talking to me as my principal right now, or my mom?"

Kimber's new boyfriend, Austin, visits Principal McCann to ask permission to take Kimber to prom. To mend past friendships, Kimber invites her childhood friend Joan to join their prom group as a "plus-two," alongside Kimber's friend Everleigh and Everleigh's older boyfriend, Luke. Shawna buys Kimber a prom dress and activates a GPS tracking feature on her daughter's phone as a precaution.

On prom night, a stretch limousine arrives driven by a man identifying himself as Dan. Dan outlines the ground rules, forbidding roughhousing, messes, and "drugs or alcohol." Once on the road, Austin reveals a smuggled bottle of alcohol and instructs Dan to divert to a secluded overlook where he and Kimber had their first date. When Dan catches the teenagers taking photos with the alcohol, he threatens to terminate the trip unless they surrender their devices: "No pictures, no phones. Not until I drop you off at the prom." The group complies and hands over their phones.

Back at the high school gymnasium, Shawna notices Kimber has missed her scheduled arrival time and fails to reach her by phone. Inside the moving limousine, Kimber notices they are heading away from the school. Everleigh and Joan test the door handles and find them locked. Luke examines the interior paneling and discovers the partition and windows are reinforced. Using tools from a boutonniere, Luke and Kimber begin dismantling the door frame to access the interior lock mechanism.

The limousine halts in the basement parking garage of Paul's office building. Dan opens the door brandishing a stun gun, shocks Austin unconscious, and forces Kimber and Joan out. Dan hands Kimber a phone locked to a single outgoing line and delivers an ultimatum: "I need you to go inside and open your father's office safe." He gives her ten minutes to retrieve a specific thumb drive, warning that if she fails, "they'll find that limo at the bottom of a lake filled with the corpses of your friends."

Kimber and Joan enter Paul's dark office suite, unlock the safe, and locate a hardware device resembling a cryptocurrency wallet. When they return to the parking garage, Kimber refuses to hand over the drive until her friends are freed. Luke lunges from the limousine to tackle Dan, but Dan overpowers and stabs him. Forcing Kimber and Joan back inside the vehicle, Dan snatches the drive and warns, "She dies next if you don't get back in now."

Guided by Kimber's GPS signal, Paul and Shawna drive into the woods, where they find a discarded pile containing all five teenagers' mobile phones. Moments later, Paul receives a call from his office security guard reporting that Kimber was seen breaking into his safe. Paul rushes with Shawna to his office and discovers his safe emptied. When Shawna asks what was taken, Paul states, "Shawna, they took everything I've ever worked for."

Inside the limousine, Joan hyperventilates and suffers an acute asthma attack. Kimber pounds on the front partition, shouting, "She's my friend. She'll die without her inhaler!" Dan slides the partition open to pass the inhaler through. Everleigh attempts to grab him, prompting Dan to trap her neck in the partition until Kimber surrenders the drive back to him.

While waiting for police at his office, Paul reveals to Shawna that he was diagnosed with prostate cancer following their divorce. Seeking financial security for his family, he had invested his savings into cryptocurrency. Detective Gosselin arrives to take their report just as Paul receives an incoming video call on his phone.

The limousine pulls over on a desolate road. Austin steps outside claiming he will confront Dan, but scuffling sounds and a gunshot follow. Dan returns alone, telling the girls, "He wasn't good enough for you." A passing police cruiser pulls up behind the limousine to investigate. Dan tells the officer that a passenger had too much to drink, but when the officer peers inside, Dan ambushes and kills him with the stun gun.

Austin appears on the video feed transmitted to Paul, Shawna, and Detective Gosselin, revealing that he faked his death and orchestrated the plot with Dan, who is his brother. Austin identifies their late mother as Grace Adams, an acquaintance Paul had an affair with before his divorce. Austin accuses Paul of driving her to an overdose: "You abandoned her. You lied to her about your family, and that betrayal killed her." Austin demands the passcode to the crypto wallet under threat of Kimber's life. Paul capitulates and recites the code: "51227924."

After transferring millions of dollars into their account, Austin steps out to help his brother pack. Kimber slips into the passenger cabin of the limousine to free Joan and Everleigh. Everleigh finds a phone dropped on the floor and transmits their GPS coordinates directly to Paul's phone before hiding in the shadows.

Dan re-enters the limousine alone to speak with Kimber, revealing that his real name is Emerson and that he only aided Austin because "he's the only family I have left." Emerson admits he was the driver who attempted to kidnap Kimber outside the college party months prior. While Emerson attempts to slow-dance with Kimber, Joan and Everleigh ambush him from behind.

The three girls lock Emerson out, climb into the driver's seat, and start the engine. Austin intercepts them in another vehicle, blocking their path with a spare set of keys in hand. Austin refuses to let the vendetta go, advancing on the limousine with intent to kill.

Paul and Shawna arrive in their car and ram Austin's vehicle, disabling it. Police cruisers arrive with sirens blaring, securing the scene and taking Austin and Emerson into custody. Paul hands Kimber her retrieved phone, and the McCanns prepare to return home together.
