What's the story?
Elle (Reese Witherspoon) hires a detective to find the biological mother of her dog, Bruiser, so she can invite Bruiser's family to her wedding. She finds out that his mother is in a lab for testing cosmetics on animals. When she urges her law firm to oppose the use of animal-testing in cosmetics (the movie is careful to stay away from the issue of animal testing for medication), she is fired. So, Elle heads to Washington determined to get legislation passed ("Bruiser's Law"), freeing Bruiser's mother and all of the other lab animals.
