Wall to Wall follows Woo Sung (Kang Ha Neul), an ordinary salaried employee who manages to purchase his own home — an 84-square-meter apartment — only to be tormented by a mysterious noise from upstairs.

The stills depict the tension surrounding apartment noise, where Woo Sung (Kang Ha Neul), representative resident Eun Hwa (Yeom Hye Ran), and Woo Sung's upstairs neighbor Jin Ho (Seo Hyeon Woo) clash. Initially filled with bliss to finally buy a house, Woo Sung finds himself stressed by noise and suspicion from the downstairs neighbor, who calls him the culprit. Determined to find the source of the noise, Woo Sung confronts Jin Ho, whose menacing demeanor piques curiosity about whether he is indeed responsible for the noise.

Facing the upcoming GTX installation, Eun Hwa, the resident representative, strives to avoid disturbance in the apartment, but suspicion between neighbors intensifies.

Kang Ha Neul shared, "Woo Sung becomes extremely sensitive and feels like he's falling apart because of the noise. While filming the scene where he lashes out after being pushed to the edge, I thought to myself, 'Have I ever played a character who breaks down to this extent?'"

Yeom Hye Ran commented, "On the outside, Eun Hwa seems kind and supportive, but deep down, she hides her ambition. I strived to maintain those subtle expressions here and there."

Seo Hyeon Woo said, "Jin Ho looks like he's been through a lot. I even gained weight and worked on creating a solid texture [for the character]."

Director Kim Tae Joon remarked, "Wall to Wall is a story where [people's] various desires collide within the most quintessentially Korean space. I hope viewers will enjoy the tremendous acting energy that the three leads bring to this vertical, confined setting."

Wall to Wall will be released on July 18, only on Netflix.
