The Plot: When Family Becomes Your Worst Enemy
“Sister” follows three individuals trapped in a deadly kidnapping scheme with shocking connections. Hae Ran (Jung Ji So) kidnaps her own sister So Jin (Cha Joo Young) for a massive ransom, orchestrated by the calculating Tae Su (Lee Soo Hyuk). But as the plan unfolds, hidden truths emerge about their relationships and motivations.
The film explores a chilling premise: What happens when the person planning your abduction is your own blood? As So Jin fights desperately to survive, the lines between victim, accomplice, and villain blur in unexpected ways.
Lee Soo Hyuk’s Transformation
Known for his suave roles in romantic series like Doom at Your Service and Tomorrow, Lee Soo Hyuk completely reinvents himself as Tae Su—a kidnapper who meticulously plans every detail in pursuit of wealth.
Newly released stills from Soompi showcase his intense presence. In one image, his sharp gaze fixed on someone across from him reveals a man in complete control. Every gesture, every expression signals his ruthless nature as he manipulates both his victim and accomplice.
Another still positions Tae Su against a dark forest backdrop—a visual metaphor for the dangerous, isolated location where the kidnapping unfolds. The remote setting intensifies the claustrophobic tension as So Jin realizes escape may be impossible.
Meet the Cast
Jung Ji So (Hae Ran): The actress who broke hearts in Parasite and Reborn Rich takes on a morally complex role as the sister willing to betray family for money. Her character’s motivations and relationship with Tae Su drive the film’s central mystery.
Lee Soo Hyuk (Tae Su): The 6’2″ actor leverages his imposing presence to create a villain whose coldness feels unnervingly realistic. This marks his first major theatrical release since transitioning from runway model to respected actor.
Cha Joo Young (So Jin): Known for Hospital Playlist and Our Beloved Summer, Cha plays the hostage fighting for survival. Her character’s desperation contrasts sharply with Tae Su’s calculated control.
Why This Role Matters for Lee Soo Hyuk
After building a career in supporting roles across K-dramas (Born Again, Sweet Home, Grid), Lee Soo Hyuk is finally getting the meaty leading villain role that showcases his range. His performance in “Sister” could redefine his career trajectory—much like how Park Hae Soo’s turn in Squid Game elevated his international profile.
The actor’s modeling background gives him a unique advantage: he understands how body language and stillness can convey menace. Where some actors rely on shouting or dramatic gestures, Lee Soo Hyuk’s Tae Su appears most dangerous when perfectly composed.
