简介：A youthful maiden is penning a series of tender missives, weaving the tale of "O" for her beloved's enjoyment, yet it appears to be as much a contest of wits. "O" is a renowned fashion photographer, who finds herself captivated by Rene, a man of considerable wealth. Rene introduces her to the opulent manor of Sir Stephen, where, for several weeks, alongside other women, she finds herself ensnared in a web of bondage. She is subjected to the cruelties of Sir Stephen, Rene, and their clique, enduring torture, degradation, and unspeakable sexual aggression.

In time, Rene returns her to her former life, yet she remains steadfast in her affection for him. She has come to understand that in the throes of love, "one is never truly free."
