Lucy, a monodrama composed for baritone and chamber ensemble by John Glover and Kelley Rourke, tells the story of psychologist Maurice Temerlin, who, along with his wife Jane, adopted a day-old chimpanzee in 1964. Naming her Lucy, their intention was to raise this chimpanzee as if she were their human child.

In the opera, as Temerlin struggles to hold on to memories of a happy family life, documentation from the experiment challenges him to come to terms with the project's ultimate consequences. In revealing the devastating effects of the experiment, the opera challenges audiences to consider the moral and ethical questions of animal research.
