Deep in the mountains of Gangwon Province lies the "Almighty Faith Cult," a cult completely cut off from the rest of the world. Suryeon, a novice nun who fled domestic violence to join this place, lives believing the cult is her only sanctuary. Then one day, she is chosen by the cult leader as a candidate to become the "Female Christ." A sacred mission to conceive the Messiah who will save everyone. Believing this to be true, Suryeon heads to the training room to carry out God's will. However, what awaited her there was a completely different side of the once-gentle Father Kwon-hyeok. "You have no right of refusal, Sister." The touch she believed was salvation gradually turns into a command, and the mission she believed was faith slowly becomes absolute submission. Swept by fear and guilt, Suryeon still relies on Kwon-hyeok's words, clinging to the affection he offers as she slowly loses herself.
