Stanley Tucci continues his history of California with the story of Silicon Valley's troubled founder, William Shockley. Shockley was the man who first brought silicon to Silicon Valley in the 1950s. He was an undoubted genius. But he was also a hideous boss and an irredeemable racist. California wants to dazzle you with its endless sunshine and visions of the future – but that’s just a mirage. Stanley Tucci plays a hard-boiled screenwriter uncovering the full, sordid truth. He knows exactly where all the bodies are buried. Academic consultant: Dr Ian Scott, University of Manchester Written and produced by Laurence Grissell
