Inmates in Pelican Bay State Prison’s Security Housing Unit (SHU) spend 22.5 hours of the day in a windowless cell—it is one of the most notorious supermax prisons in the United States. In this short documentary, Our Voices Are Rarely Heard, the filmmakers Cali Bondad and Gabrielle Canon recorded inmates’ experiences in the facility. The film aims to provide “a cinematic glimpse of the personal anguish and monotony described by inmates living in long-term isolation,” Bondad wrote in an email.
