The kidnapping thriller film 〈Sister〉, featuring actors Jung Ji-so, Lee Soo-hyuk, and Cha Joo-young, has confirmed its theatrical release on January 28 next year. The first poster released along with the announcement captures the attention of prospective audiences by hinting at the tense confrontation between the three characters.

〈Sister〉 tells the story of 'Hae-ran' (Jung Ji-so), who kidnaps her older sister for a huge ransom, 'Tae-soo' (Lee Soo-hyuk), who orchestrates the entire plan, and 'So-jin' (Cha Joo-young), who fights for survival as a hostage, uncovering the hidden truths among them.

Jung Ji-so, Lee Soo-hyuk, and Cha Joo-young's intense transformations as three characters entangled in a kidnapping drama

First, Jung Ji-so, who has proven her wide acting spectrum through works like 〈Parasite〉 and 〈The Glory〉, takes on the role of the younger sister 'Hae-ran'. Hae-ran is a character who kidnaps her half-sister So-jin to raise funds for her sick brother's surgery, and Jung Ji-so is expected to portray the complex emotional changes that occur amidst the cracks in their relationship.

Lee Soo-hyuk plays 'Tae-soo', the mastermind and orchestrator of the kidnapping. With his unique overwhelming aura, Lee Soo-hyuk is anticipated to showcase a new side by completing an unprecedented villain character based on a deep voice and restrained expressiveness.

Cha Joo-young takes on the role of the hostage 'So-jin' and delivers a passionate performance. So-jin, who was kidnapped by a younger sister she didn't even know existed, becomes a crucial variable that disrupts the flow of the narrative and shakes its direction. After establishing herself as a leading actress following 〈The Glory〉, Cha Joo-young is expected to maximize suspense with her delicate yet intense acting.

The first poster released together prominently features the contrasting expressions of the three characters. The tense face of Hae-ran, the meaningful gaze of Tae-soo, and the terrified expression of So-jin convey the psychology of each character placed in different situations. In particular, the tagline "I kidnapped my sister today" suggests a complex narrative hidden between the half-sisters and a man, stimulating curiosity beyond a simple crime.

With a dense psychological confrontation unfolding in a closed space and unpredictable developments, the film 〈Sister〉 is set to meet audiences on January 28.
