When psychologist Ayan begins treating a patient named Maya with psychological problems, their therapeutic process blurs the fragile line between memory and hallucination. Initially, Ayan simply wants to unravel Maya's fragmented thoughts through clinical methods, but ultimately becomes trapped in a labyrinth of manipulation, obsession, and truth, the truth of which is dangerously difficult to confront.

As the boundaries between doctor and patient gradually dissolve, Ayan discovers that the human mind may be the most cunning prison in the world.
