The Quiz Show Scandal

Im Yeon-yi appears to intentionally fling herself into the fast lane on the Gangbyeon Expressway. While the exact reason isn't fully detailed in the summary, her action sets the entire chain of events in motion, bringing together the four different groups whose fates become intertwined. Her seemingly deliberate act raises questions about her mental state and what led her to such a desperate measure.

The memory stick belongs to the dead woman, Im Yeon-yi, and contains the answer to the final question for an upcoming episode of the high-stakes Quiz Show. The show's prize money has climbed to 13.5 million dollars, making this information potentially life-changing for anyone who possesses it.

After the multi-car collision on Gangbyeon Expressway, all four groups of passengers and drivers are brought to Yongsan police station for questioning. They include Do Ho-man from the first car, the gambling-addicted couple Kim Sang-do and Jang Pal-nyeo with their daughter from the second car, criminals Lee Do-yeop and Park Sang-gil from the third car, and four members of a depression-therapy group including Kim Yeo-na from the fourth car. Additional people like hospital delivery worker Oh Cheol-ju and a drunk man named Lee Jun-sang are also brought in for questioning.

Each survivor has urgent reasons to need a large sum of money. Do Ho-man's wife lies in a hospital coma and needs expensive medical care while his relationship with his son is strained. Kim Sang-do is drowning in gambling debt. The depression therapy group members each have their own financial or emotional struggles. The memory stick with the final answer gives them a legitimate chance at winning the 13.5 million dollar prize, transforming desperation into opportunity.

During the live broadcast, the contestants discover that the Quiz Show organizers are running their own private scam, exploiting the participants' desperation for wealth. The show appears legitimate but is actually manipulating contestants for the organizers' own profit, turning the game into a predatory scheme rather than a fair competition.

Do Ho-man's wife lies in a hospital coma following the accident. His relationship with his brilliant but brash son Ji-yong is strained by the pressure and fear surrounding his wife's condition. The crash becomes a turning point that tests family loyalty and the cost of trying to protect what remains of their family.

Kim Sang-do is a gambling addict whose reckless appetite for gambling has left him with significant debt. His wife Jang Pal-nyeo constantly nags him about his problem, and their young daughter is caught in the crossfire of their financial turmoil. The accident forces these marital tensions into the open, and the Quiz Show represents his chance to pay off his debts.

Lee Do-yeop and Park Sang-gil are hardened criminals in the third car who have a history of "fixing" problems for money. Their willingness to use others for profit places everyone at risk. Their criminal mindset creates additional tension in the police station as they calculate how to leverage the memory stick for their own gain.

Kim Yeo-na is one of four members from a depression-therapy group who were traveling together in the fourth car. The group includes the club president, a high-school student, a French teacher, and a mobile phone sales representative. Their car becomes a space where vulnerability and confession meet calculation under crisis, as each person weighs their need for empathy against the lure of the prize money.

Under the pressure of the live broadcast, unlikely alliances form and dissolve as contestants calculate who to trust and who to outmaneuver. The summary describes shifting alliances where people pool trivia and share suspicious glances. Hidden debts, guilt, and longing for a better life drive choices that could ruin futures. The line between teamwork and exploitation blurs as survival takes precedence.

The ending leaves the group fractured as the memory stick contents, the show's hidden agenda, and the characters' concealed motives collide. The result is described as a meditation on luck, leverage, and the slippery line between ambition and danger. The night forces ordinary people to confront extraordinary stakes, with the outcome suggesting that gains come with significant losses rather than simple victory.

The Quiz Show prize money has climbed from ten million to thirteen and a half million dollars by the time the memory stick is discovered. This massive prize is what drives all the accident survivors to desperately prepare for the broadcast, as it represents a life-changing sum for people in desperate financial situations.
