The sequel to Chinatown (1974) finds J.J. "Jake" Gittes investigating adultery and murder, and the money that comes from oil.
After the war, L.A. private eye Jake Gittes is hired by realtor Jake Berman. He proves the infidelity of Berman's wife Kitty and sets up a way for her to be caught in the act. At the rendezvous, Berman shoots the co-respondent who turns out to be his business partner. Gittes finds himself in the middle of a complicated web, under pressure from all sides for a wire recording of the fatal encounter. He then realises that the land the partners were developing was once an orange grove connected with a case that he has never quite gotten over.
