After suffering a tragedy at the hands of a violent criminal group, a blind Kang Gi-beom receives an operation for a special new pair of eyes.

On a team mission at the ARGOS leader's wedding, Gi-beom runs into someone who haunts his memories. Hwang Deuk-gu is tired of playing underling.

While ARGOS leadership engages in a power struggle, Gi-beom wonders about the origins of a dangerous device retrieved from a dead man's head.

Gi-beom's disobedience comes with consequences. When Deuk-gu unleashes chaos at a jazz club, Lee Gwang-cheol faces a chilling situation.

Left with no one to trust, Choi Ye-won realizes she needs protection. An alarming package leads the team toward a horrific ARGOS hideout.

After planting a listening device, Gi-beom makes an unexpected discovery. Han Tae-woong recalls the tragedy that brought him to RUGAL.

A high-level RUGAL employee is kidnapped. Song Mi-na sets out to bring him back, but soon comes across trouble of her own.

Gi-beom finds himself trapped. While trying to pinpoint his whereabouts, the team ends up at a crowded park — and witnesses a scene of terror.
