Kim Miller loves animals, which is just as well, because her parents run their animal agency from their home. They have two trained dogs themselves, but also provide other animals for media work. When Kim's not at school, she helps train the animals and often goes along on location or to the TV studios as an assistant to her mum and dad. Casper the Golden Retriever has got a walk-on part in Kim's favourite soap opera - and Kim's allowed to visit him on set! But the teen star of the show thinks it's funny to secretly sabotage Casper's scenes. Now Casper could be replaced by another dog. Can Kim prove he's not to blame?
