Into The Valley opens on the day in July 1967 when B decides to pass her first counterfeit cheque and flee San Francisco. B is caught between generations - unmarried at 30, she doesn't understand the new counterculture youths, but never fit into her mother's world either. The only relief comes in handling the illicit cheques and endless driving in the valley. As she travels the bare, anonymous landscape, meeting an array of other characters, B's flight becomes that of a woman unravelling.
