Unlocked

Unlocked (2023) is a Korean thriller you can watch online on iFILM. Directed by Kim Tae-joon, the film is built around a premise that is uncomfortably plausible: a woman drops her phone, the wrong person picks it up, and within hours he has access to her entire life.

Chun Woo-hee plays Na-mi, whose lost handset becomes the key to her passwords, her address, her movements and everyone she knows. Im Siwan plays the man who found it — and the performance works because he doesn't play the villain as unhinged. He's calm, deliberate, and that's more disturbing than any explosion of menace. Kim Hee-won handles the detective thread that runs alongside the main chase.

The film understands that the modern phone isn't a device — it's the person. That single insight drives the whole thing, and the script is disciplined enough not to wander. Efficient, tense Korean genre filmmaking, well-suited to one sitting. Stream Unlocked (2023) online on iFILM.
