D.P.
An Jun-Ho (Jung Hae-In) is a soldier. He is quiet and calm, but inflexible. Sergeant Park Beom-Gu (Kim Sung-Kyun) notices Private An Jun-Ho's tenacity and ability to observe. He transfers An Jun-Ho to the D.P. (Deserter Pursuit) team. Their mission is to catch deserters. An Jun-Ho works with Sergeant Park Beom-Gu and Corporal Han Ho-Yeol (Koo Gyo-Hwan) on the team. Sergeant Park Beom-Gu looks tired all the time. He curses and nags at An Jun-Ho and Han Ho-Yeol, but he also takes care of them with his keen insight. Han Ho-Yeol sometimes gives An Jun-Ho investigative know-how, but he sometimes annoys him.
Meanwhile, First Lieutenant Lim Ji-Seob (Son Seok-Koo) only cares about his success in the military. He does not care for the D.P. team.
