Wall to Wall

Noh Woo-sung is a typical office worker who has finally achieved the South Korean dream of owning his own 84-square-meter apartment. To fund the purchase, he drained his life savings and took out multiple high-interest loans. However, his new home quickly becomes a psychological nightmare as he is plagued by mysterious, untraceable noises coming through the walls. As his neighbors begin to accuse him of being the source of the disturbance, the tension escalates into Hostility. Woo-sung teams up with a suspicious upstairs neighbor to uncover the source of the sounds, only to discover that the building hides secrets far more dangerous than simple plumbing issues or thin walls.
