Plot
Wall to Wall centers on Woo-seong, a diligent office worker who achieves what many in South Korea consider the ultimate dream: buying his own apartment. However, this dream comes at a steep cost. Woo-seong exhausts every financial resource—his savings, stock investments, loans, and even his mother’s garlic farm—to secure an 84-square-meter (1,140 sq. ft.) unit, the most common apartment size in Korea.
Initially, Woo-seong is filled with pride and hope. But his joy rapidly turns to dread as he is tormented by relentless, unidentifiable floor noise from neighboring units. The psychological pressure escalates, leading to sleepless nights, paranoia, and mounting conflicts with other residents. Desperate for answers, Woo-seong teams up with his upstairs neighbor, Jin-ho, to uncover the source of the disturbances. Their investigation reveals a web of secrets, hidden animosities, and even a murder mystery lurking within the walls of the seemingly ordinary apartment complex.
Key Themes:
- The psychological toll of urban living
- The fragility of human sanity under financial and social pressure
- Urban alienation and the darkness beneath everyday life
- The real-world issue of “floor noise” disputes in Korean apartments
