Apartment living can be a nightmare: sky-high rents, neighbors whose favorite hobbies are apparently moving furniture 24/7, energy bills so astronomical you contemplate living in darkness. And for one resident in Seoul, it’s about to get much, much worse. In Wall to Wall, a financially burdened homeowner who’s losing sleep because of his noisy neighbors sets out to find who’s keeping him up at night — and stumbles into way more than he bargained for. Directed by Kim Tae-joon (Unlocked), the thriller film stars Kang Ha-neul, Yeom Hye-ran, and Seo Hyun-woo.

What happens in Wall to Wall?
It’s incredibly competitive in Seoul’s fierce real estate market, but Woo-sung (Kang) is determined to make an investment. So he scrapes together every cent he has to purchase the apartment he’s been renting — and it changes everything. Except … not for the better. Every night, Woo-sung is kept up late at night by sounds from his upstairs neighbors, and every night his fury grows. As he ventures through the building again and again to locate the source of his distress, he meets a persuasive penthouse owner, Eun-hwa (Yeom), and his intimidating upstairs neighbor, Jin-ho (Seo). But can these new acquaintances really be true allies in Woo-sung’s fight for peace and quiet? Turns out, in this massive high-rise, there might not be a single person he can trust.
