Some setting details
I looked through the back posts and I don't see an actual date for this game defined. Just the Golden Age of Hollywood. Since Wikipedia defines that as from 1927 (talkies) to 1960's, I am going to specify that this is the early summer of 1952. (Unless that derails the other story line)
Beneath sunny California skies, Americans enjoy a new era of common prosperity, industry, conformity and leisure. The entertainment business is in full swing: studios churn out wholesome fare for the big screen, little screen, and the drive-in. Restaurants and roadside attractions promise families good times around every bend in the road. In Anaheim, a kingdom devoted to the dreams of childhood opens its gates to the delight of millions. However, the brighter the glare, the more startling the shadow. The nocturnal world of Los Angeles conceals a seedier side of life, despite the bright lights and gleaming motorcars that are everywhere.
If this suits, I think we're ready to get going.
