Underground
Seung-hyeon, a construction team leader with PTSD, is ordered to inspect Dohak Station, where a fatal accident halted work years ago. Inside the eerie, abandoned tunnels, he and Joo-young encounter two mysterious workers and become lost while trying to escape. Meanwhile, a CEO and a shaman perform a ritual to resume construction, but enraged spirits retaliate, plunging everyone into chaos.
