Gun-Woo (Gang Dong-won) is an honest and hardworking deliveryman, who even received a model citizen award for saving a singer from a robbery. Out of the blue, his old friend Moo-Yeol visits him at work. In a brief moment to enjoy the exciting surprise, Gun-Woo witnesses a bombing incident that kills a presidential candidate right in front of him. Moo-Yeol tells Gun-Woo that he is responsible for the bombing and that everyone will come after him as part of the agency’s plan to frame him. Gun-Woo manages to escape the scene, but all the evidence, including security camera footage, eyewitness testimonies, and fingerprints, point towards him as the suspect. He encounters former secret agent Mr. Min (Kim Eui-sung), a former friend of Moo-Yeol, who helps clear his name. Gun-Woo must fight with all his might to survive. However, as he tries to flee, the people around him are put in dangerous situations, including his old friends Dong-Kyu (Kim Dae-myeung), Geum-Chul (Kim Sung-Kyun), and Sun-Young (Han Hyo-joo).
