Deep in the mountains of Gangwon Province lies the Church of Almighty Faith, a cult cut off from the outside world. Sister Su-ryeon fled an abusive home to join it, believing the church is her only sanctuary. When she’s chosen as a candidate for the Female Christ, tasked with conceiving the messiah, she heads to the instruction room ready to fulfill her sacred mission. But there, the gentle Father Kwon Hyeok reveals a side she’s never seen, and refusal is not an option. What she believed was salvation turns into submission, and with every lesson, Su-ryeon loses a little more of herself.
