Amber cannot help worrying about her kitten, Cleo, while she is at school all day. Cleo, the kitten, loves to explore, and when she learns to climb over the wall into the front yard, there are so many ways for her to get into trouble. One day, Cleo sees that a builder has left his van door open, and she climbs inside to investigate. Before the curious little kitten knows it, the door slams shut, and the van sets off. Cleo eventually escapes, but she has no idea where she is or how to get home. Will she ever find her way back to Amber?
