Cannibal Women in the Avocado Jungle of Death (1989)

The government hires a feminist at the local university to track down the Piranha Women living in the uncharted Avocado Jungle (westernmost outpost is San Bernardino) to convince them to move to a reservation condo in Malibu.

She hires a guide at the edge of the jungle, a male chauvinist pig, and they have many arguments about men and women as they work their way in, and eventually confront the Piranha Women.
