Will (Jude Law) has a thriving landscape architecture firm which he runs with his friend, Sandy (Martin Freeman). Professionally, things could not be better but Will spends less and less time at home with his beautiful, melancholy partner, Liv (Robin Wright Penn) and her troubled 13-year-old daughter, Bea. Will's office has recently relocated to King's Cross, the center of Europe's most ambitious urban regeneration site and their state-of-the-art studio repeatedly attracts the attentions of a local gang of thieves.
After one of the break-ins, Will follows teenaged parkour enthusiast Miro (Rafi Gavron) back to the apartment he shares with his mother, Amira (Juliette Binoche), a Bosnian refugee. With his relationship already in crisis, Will embarks on a passionate journey into both the wilder side of himself and the city in which he lives.
