Each week retired polytechnic lecturer Sandra Kyle visits two local meatworks to conduct (usually solitary) vigils for animals on their way to slaughter. A committed vegan and local representative of the international Animal Save Movement, she 'bears witness' as animal trucks arrive and tries to provide some comfort to the animals by making eye contact with them and by singing, playing music, and reciting mantras. Her objective is to close down all animal slaughterhouses in New Zealand by the year 2025; these aims are outlined in her self-published book Glass Walls.
