Philip K. Dick's Electric Dreams The Hood Maker

In an authoritarian regime called the Free Union, a minority of humans have developed telepathic abilities. Mistrusted by society, they are referred to as "Teeps", live in ghettos, and are routinely discriminated against. A telepath named Honor is recruited to work for the police, and forms a close relationship with her handler, Agent Ross. The pair investigate when a mysterious individual calling himself the "Hood Maker" begins distributing telepathy-proof hoods throughout the city.
