Adapted from author David Nicholls' critically acclaimed novel of the same name, director Lone Scherfig's ONE DAY stars Anne Hathaway as a principled working-class girl who forges a unique bond with a wealthy jet-setter that spans two decades. July 15, 1988: Emma (Hathaway) is about to enter the real world. An idealist from humble upbringings, she dreams of making the world a better place for everyone. On the night of her graduation, Emma (Hathaway) meets Dexter (Jim Sturgess), a wealthy flirt without a care in the world. Dexter is also graduating, though unlike Emma he looks forward to a future of comfort and privilege. By checking back with Emma and Dexter every July 15th for the next 20 years, we experience their happiness, hardships, and heartache as they strive to live out their dreams, and find meaning in a world that's constantly changing.
