Heart-Pounding Island

Seo-hoon is a third‑year, completely unknown idol. When illegal hidden‑camera footage of his far more successful idol younger brother, Eloy, is leaked, Seo-hoon attacks the idol who mocked his brother live on air. Soon after, Eloy takes his own life, and Seo-hoon’s career and life both crash to the bottom. “Heart-Pounding Island” is an extreme survival reality show set on an uninhabited island, bringing together disgraced celebrities whose lives have fallen apart after scandals—people just like Seo-hoon. “You’ll find the one who ruined Eloy’s life there.” Led by a mysterious phone call with that message, Seo-hoon joins the 10‑day show, determined to uncover the truth behind his brother’s death.
