Love and espionage collide in this drama of the National Intelligence Service's rookie agents. Han Gil-ro (Joo Won) realizes his dream of becoming an international man of mystery, after a childhood spent poring over James Bond films. Kim Seo-won (Choi Kang-hee) spices things up as a goofy, yet determined agent, but it's not all 007 glamor. Both Gil-ro and Seo-won must learn what it takes to uphold their sworn duty, even at the sacrifice of their happiness â and lives.
