Mantis is a 2025 South Korean action-thriller film set in the same universe as the 2023 hit Kill Boksoon. The story follows Han-ul (played by Im Si-wan), a top-tier assassin who returns from a brief hiatus to find the contract killer industry in turmoil after the sudden death of its CEO, Cha Min-kyu. Re-entering this chaotic world, Han-ul encounters his former trainee and rival, Jae-yi (Park Gyu-young), and the legendary retired killer Dok-go (Jo Woo-jin). As they vie for dominance in the assassin hierarchy, old friendships are tested, and deadly rivalries emerge. Wikipedia
