The Quiz Show Scandal

On a tense late-night stretch along the Gangbyeon Expressway toward Seoul, a multi-car crash erupts as a young woman, Im Yeon-yi, seems to fling herself into the fast lane. The collision pulls four very different groups into a single thread of fate and consequence. The immediate chaos leaves drivers and passengers grappling with injuries, fear, and the unsettling sense that every choice will be scrutinized later.

In the first car, Do Ho-man's life narrows to crisis and memory as his wife lies in a hospital coma. The pressure splits his relationship with his brilliant, brash son Ji-yong, who bears the weight of his father's fear. The crash becomes a test of loyalty, memory, and the cost of trying to protect what remains.

In the second car, a gambling-addicted husband and his nagging wife struggle over debt, luck, and their daughter's safety. The marriage threads apart under stress, and the accident forces painful truths into the open. The couple's choices now carry consequences beyond their own lives.

In the third car, hardened criminals Lee Do-yeop and Park Sang-gil reveal a willingness to fix problems for money, brushing past others' safety. Their reckless pragmatism drags bystanders into danger and sets up a volatile mix of fear and greed. The collision reveals how easily predatory motives can ride along with desperation.

In the fourth car, four members of a depression-therapy group sit shoulder-to-shoulder, exposing vulnerabilities: a club president, a high-school student, a French teacher, and a mobile phone salesman. The car becomes a microcosm of insecurity, where confession meets calculation under crisis. Their need for empathy competes with the lure of a life-changing fortune.

All four cars—and others pulled in for questioning—arrive at the Yongsan police station to sort out what happened. Investigators begin to peel back motives, with Oh Cheol-ju and a drunk Lee Jun-sang among the questioning parties. The room becomes a maze of shifting loyalties as everyone realizes they are both suspects and witnesses.

The investigators uncover a startling detail: the dead woman had lined up questions for a high-stakes Quiz Show, and a memory stick tucked in her bag contains the answer to the final question. The discovery turns the room into a race for wealth, reframing motives from sympathy to calculation. The potential windfall sharpens everyone's competitive edge.

With the memory stick as their beacon, the group begins brushing up on general knowledge, pooling trivia from decades of memory. People form shifting alliances, testing loyalties as they chase a chance at millions. The room becomes a tense workshop where intellect, nerves, and desperation collide.

As the live Quiz Show broadcast begins, the organizers reveal their own private scam, exploiting the contestants’ desperation for wealth. Trust shatters as the show itself becomes a battlefield of manipulation and nerve. The contestants realize they may be pawns in someone else’s profitable game.

Under the studio lights, unlikely alliances form and brutal calculations emerge as contestants decide who to trust and who to outmaneuver. Hidden debts, guilt, and longing drive choices that could ruin futures. The line between teamwork and exploitation blurs as survival takes precedence.

As the show nears a conclusion, the personal costs of chasing fortune become clear for each passenger. Debts, guilt, and the longing for a better life influence decisions under pressure. The tension shifts from clever answers to the consequences those answers entail.

The memory-stick contents, the show’s hidden agenda, and concealed motives collide, fracturing the group’s fragile trust. People confront what they’re willing to sacrifice for a shot at millions. The night ends with a grim realization that luck is slippery and ambition dangerous.
