Mantis (2025) Sinhala Subtitles
“Mantis” (Samagwi – 사마귀), which was released worldwide on Netflix in 2025, is a unique film that has added a new chapter to the action and crime genre of South Korean cinema. This work, which belongs to the universe of the extremely popular film “Kill Boksoon” in 2023, is presented as a spin-off that takes place in the same world. Directed by Lee Tae-sung and written by “Kill Boksoon” creator Byun Sung-hyun, it features a veteran cast of actors. Im Si-won, Park Gyu-yong, and Jo Woo-jin are among the main ones.
Plot
The film’s story revolves around Lee Han-ul (Im Si-won), a highly skilled assassin known by the nickname “Mantis”. Returning to the profession after a long break, he finds the world of assassins in complete chaos. The rules and the dominance of the powerful are broken, and each assassin is engaged in a fight to assert his power.
In the midst of this chaos, Mantis encounters his old training partner and fierce competitor, Shin Jae-yi (Park Gyu-yong). Although she is a skilled assassin, she is constantly jealous of Mantis’s skills, and she maintains a complicated relationship with him. Meanwhile, retired but legendary Dok-go (Jo Woo-jin) also returns to the scene to be part of this power struggle.
The fierce and cunning competition between these three for the number one spot in the world of assassins is the main theme of the film. As old friendships are tested, new alliances are formed and broken, and their efforts to defeat each other are presented in a wonderful way, blending action, humor, and drama. “Mantis” is characterized by a more humorous and light-hearted nature than “Kill Boksoon”.
Analysis
“Mantis” is not just an action film. It is a story that examines the lengths to which people will go for power, loyalty, and survival. Im Si-won, as “Mantis”, shows the outward appearance of a ruthless killer, but also shows a human side to his character. Park Gyu-yong’s “Jae-yi” stands out as a complex female character who oscillates between talent and jealousy.
With its highly creative fight scenes, fast-paced plot, and deep psychological conflicts between characters, “Mantis” brings a fresh perspective to the Korean action genre. It is a film that will appeal to fans of “Kill Boksoon” and fans of series like John Wick.
