In the early 1960's, sixteen-year-old Jenny Mellor (Carey Mulligan) lives with her parents in the London suburb of Twickenham. On her father Jack's (Alfred Molina's) wishes, everything that Jenny does is in the sole pursuit of being accepted into Oxford, as he wants her to have a better life than him. Jenny is bright, pretty, hard working, but also naturally gifted. The only problems her father may perceive in her life is her issue with learning Latin, and her dating a boy named Graham (Matthew Beard), who is nice, but socially awkward. Jenny's life changes after she meets David Goldman (Peter Sarsgaard), a man over twice her age. David goes out of his way to show Jenny and her family that his interest in her is not improper and that he wants solely to expose her to cultural activities which she enjoys. Jenny quickly gets accustomed to the life to which David and his constant companions, Danny (Dominic Cooper) and Helen (Rosamund Pike), have shown her, and Jenny and David's relationship does move on to becoming a romantic one. However, Jenny slowly learns more about David, and by association, Danny and Helen, and specifically how they make their money. Jenny has to decide if what she learns about them and leading such a life is worth forgoing her plans of higher education at Oxford.
