The Story So Far — And What’s Next
The Roundup series is Korea’s longest-running action franchise, centered on detective Ma Seok Do as he takes down various criminal organizations. Think of it as Korea’s answer to a classic cop thriller — raw, relentless, and impossibly entertaining.
In The Roundup 5, Ma Seok Do — now promoted to team leader of the Major Crimes Investigation Unit — faces Lee Kang Tae, the mastermind behind the most dangerous criminal operation yet, in what’s described as an extreme showdown against increasingly evolved crimes.

What makes this installment extra special? Ma Dong Seok himself took part in writing the screenplay and production, showing just how deeply invested he is in this franchise.
This is the kind of action film franchise that keeps raising the bar with every entry — and The Roundup 5 looks no different.
Same Director, Bigger Stakes
Director Heo Myeong Haeng, who previously handled the series’ action choreography and directed the fourth installment, returns to helm this one again — so fans can expect the same hard-hitting, fist-first filmmaking they’ve come to love.
