The Roundup: Punishment

Ma Seok Do, also known as "Monster Cop" (Ma Dong Seok), is back in action! This time, he's up against Baek Chang Ki (Kim Mu Yeol), a ruthless former mercenary who runs an illegal online gambling organisation.

With the help of the Cyber Investigation Team, Ma Seok Do begins to track down Baek Chang Ki and his network. Their investigation takes them to the Philippines, where they discover a connection between a drug trafficking app and an online gambling network.

Baek Chang Ki proves to be a dangerous enemy, using violence and intimidation to maintain his power. He doesn't hesitate to use kidnapping, assault, and murder to eliminate anyone who stands in his way.

To further complicate matters, Baek Chang Ki has the support of Jang Dong Cheol (Lee Dong Hwi), an IT genius who plans to run a similar scheme on a larger scale in Korea. Now, Ma Seok Do and his team must act quickly to stop this threat and protect innocent victims from harm.
