The plot traces the relationship between recent college graduate, Anastasia Steele, and manipulative billionaire, Christian Grey. Steele is required by Grey to sign a contract allowing him complete control over her life as well as a non-disclosure agreement, something that he has required from all of his previous submissives. Upon learning that she is a virgin, Grey agrees to have sex with her in order to prepare her for later encounters, fully intending that the contract would be signed. As she gets to know him, she learns that his sexual tastes involve bondage, domination, and sadism, and that childhood abuse left him a deeply damaged individual. In order to be his partner, she agrees to experiment with BDSM, but struggles to reconcile who she is (a virgin who has never previously had a boyfriend) with whom Christian wants her to be, his submissive and a to-do-with-as-he-pleases partner in his “Red Room of Pain”.
