Seong-gyu, Jo Woo-jin, a branch manager at a Busan bank, drives to work with his daughter Lee Jae-in Hye-in, who is about to take her entrance exam. He answers a call on a hidden glovebox phone from a restricted number, a so-called black call, warning that there is a bomb under his seat and that any move to exit will trigger the explosion. The city’s bustle around them fades into a claustrophobic countdown as a routine ride turns into a nightmare in downtown Busan.
It is later revealed the mysterious caller is Jin-woo, Ji Chang-wook, a former employee of the chemical factory where Seong-gyu orchestrated an investment that funded his rise to branch manager. The workers who lost their savings pursued lawsuits but could not recover their money, and some were driven to despair. Jin-woo’s wife committed suicide along with their unborn child because of the scandal, fueling his thirst for revenge against Seong-gyu.
As the danger escalates, the past’s truth comes into sharper focus: the bank’s greed and deceit left ordinary people ruined. The clock ticks relentlessly, and Jin-woo’s threats push Seong-gyu toward a deadly choice: drive the car into the river and end it all, or fight back to save the lives at stake while facing consequences for his own crimes. In a tense reversal, Seong-gyu manages to pull them from the edge of disaster and makes a bold decision to surrender to the police, hoping to expose the scam and begin atonement for his role in the scheme.

In the bustling streets of Busan, a seemingly ordinary morning quickly turns into a pulse‑tighter ordeal for a family on the run. Seong‑gyu, a bank branch manager, sets out for work with his teenage daughter Hye‑in and his young son tucked safely in the backseat of his car. Their routine commute—filled with chatter about school exams and everyday life—suddenly fractures when a disembodied voice on a restricted line claims a bomb lies hidden beneath the driver’s seat, ready to explode the moment anyone attempts to leave.
The invisible threat forces the vehicle to become a claustrophobic cage, turning the city’s familiar skyline into a backdrop for a high‑stakes standoff. As traffic snarls and the sun climbs, the car becomes a moving arena where every breath, every whispered reassurance, and every glance at the ticking clock heighten the tension. The ordinary sounds of honking horns and distant chatter are muted by the deafening uncertainty of an unseen menace, creating a relentless atmosphere of dread that presses against the glass.
Against this relentless pressure, Seong‑gyu must balance his responsibilities as a father with the desperate need to protect his children while navigating an impossible dilemma: how to satisfy an anonymous extortionist’s demands without endangering those he loves. The film’s tone blends tight‑knotted suspense with an intimate portrait of familial bonds stretched to their limits, inviting viewers to wonder just how far a parent will go when the world outside the car becomes as threatening as the threat inside.
