21 year-old Anastasia "Ana" Steele is an English literature major at Washington State University’s satellite campus near Vancouver, Washington. When her roommate, Kate Kavanagh, becomes ill and is unable to interview Christian Grey, a 27-year-old billionaire entrepreneur, for the college newspaper, Ana agrees to go in and takes her place. At Christian's Portland headquarters Ana stumbles her way through the meeting. Christian, who is that year's WSU commencement speaker, takes an interest in her; soon after, he visits the hardware store where Ana works, and offers to do a photo shoot to accompany the article for which Ana had interviewed him.
Christian invites Ana for coffee, but leaves abruptly after Ana confesses to being a romantic, saying he is not the man for her. Christian later sends Ana first edition copies of two Thomas Hardy novels, including Tess of the d'Urbervilles, as a gift, with a quote from the latter book about the dangers of relationships, on an accompanying card.
Ana and her friends celebrate graduation at a local bar. After drinking too much, Ana spontaneously calls Christian, saying she is returning the books, and berating his behavior towards her. Christian goes to the bar to find Ana, who then passes out. She wakes up the next morning in Christian's hotel room, but is relieved to find that they were not intimate.
Ana and Christian begin seeing each other, though he insists that she sign a non-disclosure agreement preventing her from revealing details about their dalliance. Christian explains that he has bondage relationships, but only as clearly defined in a contract between the participants. Ana reveals that she is a virgin. While considering the agreement and negotiating her own terms, and after visiting his "playroom," a room stocked with a variety of BDSM toys, furniture, and gear, she and Christian have sex. Ana also meets Christian's mother. Ana asks Christian how many girls had lived in his house while he takes her home.
Christian bestows a series of gifts and favors upon Ana, including a new car and a laptop computer. After Ana and Kate move to Seattle, Ana continues seeing Christian. During dinner at Christian's parents, Ana suddenly mentions she is leaving the next day to visit her mother in Georgia. Later, Christian becomes frustrated when Ana says that she wants more than the one-sided relationship he proposes. She is shocked when Christian unexpectedly arrives in Georgia; he takes her flying but leaves soon afterward, to tend to an emergency in Seattle.
After returning home, Ana continues seeing Christian, who wants further sexual experimentation. Ana initially consents, but Christian keeps emotionally distant, upsetting her. While still considering the contract, and in an effort to understand Christian psychologically, Ana asks him to demonstrate how he would "punish" her for rule-breaking. Christian whips Ana's buttocks with a belt. Upset and disgusted, Ana breaks up with Christian after concluding that he is wrong for her and his practices border on deviant and excessive.
