When college senior Anastasia Steele (Dakota Johnson) steps in for her sick roommate to interview prominent businessman Christian Grey (Jamie Dornan) for their campus paper, little does she realize the path her life will take. Christian, as enigmatic as he is rich and powerful, finds himself strangely drawn to Ana, and she to him. Though sexually inexperienced, Ana plunges headlong into an affair -- and learns that Christian's true sexual proclivities push the boundaries of pain and pleasure.

Christian Grey starts getting nightmares after Anastasia Steele leaves him. While he tries to get her back into his life, Jack Hyde, Ana's editor, and Leila, a former submissive, create problems.

Believing they've left behind the shadowy figures from the past, billionaire Christian Grey and his new wife Anastasia fully embrace their inextricable connection and shared life of luxury. But just as the Greys begin to step into their new roles, sinister events come to light and jeopardise their happy ending before it even begins.
