Esteemed filmmakers D A Pennebaker and Chris Hegedus document the relentless efforts of animal rights advocate Steven Wise as he enters the courtroom for a groundbreaking legal challenge. This case aims to apply the writ of habeas corpus to extend the concept of legal “personhood” to certain animals. Wise’s extraordinary clients—chimpanzees Tommy and Kiko, who were once celebrated in the entertainment industry—are now enduring squalid conditions and fighting for survival. Wise and his fervent legal team take us on a journey, presenting compelling evidence of such mistreatment and immersing us in the complexities of their legal battle as they question traditional views on what it means to be a non-human animal.
