I haven’t spent one second of my life worrying about people squatting on my property. My wife, on the other hand, likes to tell me that squatters are a real risk and that we need to be careful and constantly on the lookout. After watching the South Korean thriller HIDE AND SEEK, I’m not saying my wife is completely right to be so concerned, but the idea of someone deciding to take over another person’s home is actually quite scary! This film takes that ordinary fear and turns it into something genuinely disturbing. Director Huh Jung finds some interesting ways to expand on that premise, creating an atmosphere where the most familiar surroundings no longer feel safe.

Sung-soo (Son Hyun-joo) has everything a man could want. He’s a successful businessman with a beautiful wife, two perfect kids, and a luxurious apartment. When he learns that his estranged older brother, Sung-chul, has disappeared, he sets out to get his belongings. In order to get his stuff, he goes to the rundown apartment complex where his brother had been living. While there, he discovers strange symbols carved beneath the doorbells of the apartments. The residents seem frightened of his brother, and nobody wants to answer his questions. Things become even more unsettling when Sung-soo returns home and discovers similar markings outside his own apartment. Sung-soo becomes convinced that someone, maybe his own brother, is stalking his family, and they are all in real danger.

Is there anything more unsettling than the thought that someone is watching you, maybe even going as far as secretly living in your home?! I take my responsibility to protect my family very seriously, and this movie leaves open the possibility that it’s not as easy as it appears. HIDE AND SEEK plays with the idea that we all seem to take our sense of security inside our homes for granted. When that safety net is taken away from us, we know that our characters are potentially in danger at all times. The idea that no place is safe, no matter how many locks we have, is disturbing and creates an effective and horrific atmosphere.

Son Hyun-joo is good as the family man whose increasingly erratic behavior makes it difficult to determine just how much of what he’s experiencing is real. Moon Jung-hee is also effective as Joo-hee, a woman he meets who is living in the rundown apartment complex where his brother lived. She is particularly scared of his brother and her circumstances become increasingly important as the story moves forward. I really like Jeon Mi-seon as Sung-soo’s wife. She’s not really prepared to have to deal with this sudden threat in her life, but when she realizes her kids are in danger, she’s about as badass as it gets.

There are a lot of good performances on display, but this is one of those movies where you think you’ve figured everything out, only to discover that things are not as simple as they appear. The story gives up its secrets piece by piece, but with enough sleight of hand that you can’t always trust your eyes. First-time writer and director Huh Jung seems to be having fun toying with us and delivers an impressive debut!

HIDE AND SEEK isn’t a perfect movie, and there are times where it stretches credibility, but there’s enough tension and freakiness here to make those shortcomings relatively easy to overlook. It’s an effective thriller that takes a familiar fear and reminds us that sometimes the most frightening thing isn’t what’s waiting outside our front door, but what might already be inside.
