21-year-old Anastasia "Ana" Steele (Dakota Johnson), a literature student at Washington State University's satellite campus near Vancouver, Washington, finds herself stepping into unexpected territory. After her roommate, Kate Kavanagh, falls ill, Ana kindly agrees to take her place and interview Christian Grey (Jamie Dornan), a wealthy entrepreneur, at his Seattle headquarters for their college newspaper.
During their meeting, Christian shares that his success hinges on his ability to connect with people, identifying their true motivations. He also reveals a controlling nature shaped by a complicated past, having been adopted at a young age. His philanthropic efforts are evident as he invests in agricultural businesses, aiming to alleviate hunger in the world. As their conversation unfolds, it's clear that Christian is intrigued by Ana, and he soon stops by her workplace to extend an offer for an internship—one that Ana hesitantly declines.
Despite this, Christian's interest continues to grow as he invites her to a photo-shoot to complement the article, leading to a coffee invitation that he abruptly cuts short, leaving Ana bewildered. Confessing she's a romantic at heart, Ana tries to connect, but Christian, wrestling with his own intensity, insists he cannot be the man for her and ultimately decides to walk away.
For her graduation, Christian surprises Ana with first edition copies of Tess of the d'Urbervilles, prompting a celebratory outing with friends. Overindulging in drinks, Ana, in a moment of spontaneity, calls Christian, who quickly arrives to ensure her safety. Waking up in his hotel room the following day, Ana feels relief when Christian assures her nothing inappropriate occurred.
However, the relationship evolves when Christian expresses that he won't touch Ana until she signs a contract, which she finds perplexing. Despite her reservations, attraction builds to an undeniable culmination as they share a passionate kiss. As they step into this complicated relationship, Christian reveals his preference for bondage, offering Ana a room in his apartment dedicated to their encounters.
Ana confides in him about her virginity, prompting Christian to ensure her first sexual experience is positive, choosing to keep their initial encounter free from bondage. But as their passionate liaison unfolds, even a taste of bondage begins to surface with Christian's gentle restraint using a silk tie. While pondering their evolving agreement, Ana becomes increasingly unsure about the intense nature of their connection, confronting Christian about his detached demeanor.
Introducing Ana to his family, including his parents, Mr. Grey and Dr. Grey, and sister Mia, Christian's past experiences leave Ana grappling with the emotional chasm between them. His lavish gifts and attempts to impress Ana—like a new car and laptop—clash with her growing discomfort as she researches the world of submissives and grapples with Christian's desires.
Faced with the terms of their unconventional bond, Ana manages to negotiate some boundaries in their contract. But Christian pressures her to experience his world before making a final decision. Their dynamic grows more perplexing as Christian continues to push physical limits, leaving Ana feeling increasingly isolated and disheartened by Christian’s reluctance to engage in a "normal" relationship.
As Ana wrestles with her feelings about the BDSM lifestyle, a turning point arises when she requests Christian to demonstrate his form of discipline. After a painful encounter with a belt, where she counts each strike, Ana's romantic dreams shatter—realizing this is not the relationship she desires.
Ultimately, Ana concludes that Christian's excesses and need for control are not compatible with her vision of love, leading her to understand that, despite the attraction, he may not be the right match for her.
