Stanley Tucci tells the story of Dianne Feinstein, trailblazing Californian politician who took over as mayor of San Francisco in 1978 after the murders of Harvey Milk and Mayor Moscone.

Feinstein was charged with the difficult task of healing San Francisco after the brutal slaying of two highly popular leaders - against the backdrop of the further horrors of the recent Jonestown Massacre.
