A filmmaker named Kabir moves into an old Mumbai apartment building where a fog-filled corridor, known as the Dhundhli Gallery, is rumored to be haunted. One night, he discovers security footage showing a ghostly girl walking right behind him. When he confronts the corridor, she appears and pulls him into the fog. The next morning, only his broken camera is found. Now, the corridor has two figures wandering in the mist — the girl, and Kabir.
