After winning a high-profile case, Irene takes a much-needed vacation to escape the relentless demands of her career. As an in-demand lawyer who has never lost a single case, she's used to the constant flood of calls, emails, and desperate pleas for help. But this time, she refuses to let work invade her solitude. A break is a break. For a while, the ocean breeze and the quiet isolation of her resthouse provide the peace she craves-until her senior calls in the middle of the night. Irene is ready to refuse, but something about the case feels different. Her senior never calls for help. And with her vacation ending soon, she has little reason to say no. She drives back to the city, straight to a five-star hotel where the crime scene awaits. In Room 0294, the horror unfolds before her eyes. A woman's body, brutalized beyond belief. Blood-soaked sheets. Lips sliced. A final act of cruelty sewed into her skin. Twenty bullets, leaving no doubt that this was not just a murder-it was a message. The investigation moves fast. Clues are gathered, CCTVs scoured, sleepless nights spent chasing the truth. And finally, they find their answer. The evidence is undeniable. The pieces fit together perfectly. The murderer has been found. But while the rest of the team celebrates the swift breakthrough, Irene feels her world tilt. Because the killer is none other than her ex-girlfriend, Seulgi. Now, Irene stands at the crossroads of justice and love. The evidence is irrefutable, yet every instinct screams that something isn't right. Is Seulgi truly capable of such monstrous cruelty? Should she fight for the truth, even if it means betraying the person she once loved? Or is the truth itself the greatest deception of all?
