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.

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