Kim Joon, a transfer student at a prestigious high school, is arrested for the murder of one of his classmates. Yoo-jin Taylor, the top student of his class, is found dead in the woods behind the school, and with strong evidence and testimonies from a close-knit group of students pointing to Joon, he still earns a release after police questioning. Returning to the campus, he abruptly turns the tables, seizing control of a tense situation and holding the group of students as prisoners in a hidden basement beneath the school.
This hidden chamber houses members of an elite circle, the top 1% of the student body who enjoy privileges that help them sustain their coveted ranking. As the truth begins to surface, flashbacks reveal the dark path that led Joon to this moment: an ambitious transfer from an ordinary high school who was desperate to join their ranks, and who was coerced into performing a cruel sequence of tasks to prove his worth. The veil lifts on how the group’s ruthless code operated, shaping alliances and testing loyalties in a climate of fear and secrecy.
The study group, known as 'Rabbit Hunt' (토끼사냥), is gradually exposed for its cruelty and crimes, and Joon takes the helm in a dangerous hostage situation. Before the confrontation, his friend, Jeong Soo-jin, tries to shine a light on their wrongdoing and reveal it to their schoolmates, but is brutally beaten by the members and left unconscious. While she lies in a hospital bed, Soo-jin’s mother discovers a letter in her daughter’s hand written by Kim Joon — a chilling clue that hints at Joon’s own death. Soo-jin’s condition eventually shows signs of life, and the scene is suffused with the sense that the truth may still emerge.
As the tension peaks, Joon passes the USB drive containing the study group’s crimes to detectives, including Detective Choi, and he grants the captors a narrow window—one minute—to make a final attempt to escape the room alongside another student. The room falls into a sudden, suffocating silence as the escape begins; then the sky outside darkens as a Total solar eclipse envelopes the area, plunging the room into darkness for several minutes.
In the darkness, Joon detonates the improvised device, an explosive charged with nitroglycerin, and the ensuing blast consumes him along with the remaining members of the rabbit-hunting circle. When the eclipse passes and the light returns, the room is left in ruins, the truth laid bare, and the school community left to reckon with the price of power, privilege, and cruelty that were allowed to fester in silence.
