In his third case, in order to stop a brutal drug war in Seoul, Ma Seok-do, a not-so-squeamish cop, must face the Yakuza and a corrupt colleague. South Korean actor Ma Dong-seok, a somehow legit heir of fist swinger Bud Spencer, one of the stars of the zombie feast TRAIN TO BUSAN, is determined to reestablish order. THE ROUNDUP: NO WAY OUT is an even more brutal action spectacle than THE OUTLAWS and THE ROUNDUP.
