Labor mouse Minnie is the product of a failed animal experiment. Minnie is beautiful, enormous, and highly intelligent. The super mouse escapes from the security lab and finds like-minded individuals. With extraordinary means, they advocate for the protection of animals and for humane research as an alternative to animal testing. Will they succeed? The adventurous story of lab mouse Minnie has a real background and provides insights into the opaque jungle of animal testing research. The vast majority of careers in biomedicine are based on animal experiments. Many experimenters have lost sight of human health. There are patents on living beings and a multimillion-dollar market for genetically modified animals, while the research into new animal-free testing methods is chronically underfunded, despite the urgent need for this research.
