KING OF THIEVES is based on the unbelievable true story of the Hatton Garden heist. A famous thief in his younger years, widower Brian Reader (Michael Caine), 77 years of age, pulls together a band of misfit criminals to plot an unprecedented burglary at the Hatton Garden Safe Deposit. The thieves, all in their 60s and 70s except for one, employ their old-school thieving skills to plan the heist over the Easter holiday weekend.
A young man named Tristan (Charlie Cox) tries to win the heart of Victoria (Sienna Miller), the beautiful but cold object of his desire, by going on a quest to retrieve a fallen star. His journey takes him to a mysterious and forbidden land beyond the walls of his village. On his odyssey, Tristan finds the star, which has transformed into a striking girl named Yvaine (Claire Danes). However, Tristan is not the only one seeking the star. A king's (Peter O'Toole) four living sons – not to mention the ghosts of their three dead brothers – all need the star as they vie for the throne.
