Set in a volatile near-future geopolitical landscape, 'Borderline Protocol' follows an elite clandestine task force operating in the ambiguous gray zones between sovereign territories. Tasked with defusing covert international crises before they escalate into open warfare, the team must navigate a labyrinth of espionage, betrayal, and high-stakes diplomacy. At the center of the conflict is Commander Kang Jin-woo, a decorated veteran haunted by past operational failures, and Dr. Elena Vance, a brilliant data security expert who uncovers a global conspiracy reaching the highest levels of multiple governments. As they race against time across international borders, they are hunted by ruthless intelligence agencies and private syndicates alike, forcing them to question who they can trust and what lines they are willing to cross.
