An Jun-ho's keen eye earns him a position in the Deserter Pursuit unit. On his first mission with Park Sung-woo, things don't go quite as planned.

Discharged from the hospital, Han Ho-yeol returns to the base and partners up with Jun-ho to search for a soldier last spotted at a subway station.

Jun-ho and Ho-yeol assist with a mission while on break. In an attempt to gain intel, the two go undercover to befriend a deserter's girlfriend.

Relentless hazing shifts Cho Suk-bong's once-warm personality. Riddled with responsibilities, an enlistee jumps the fence at the dead of night.

Suk-bong is pushed over the edge. During their investigation, the D.P. duo learns of events that unfolded at Hwang Jang-soo's discharge.

When a chase after a deserter turns into a manhunt for a criminal at large, Jun-ho and Ho-yeol rush to find him before armed men bring him down.
