Storm is having difficulty at cadet school. As Bushytail's daughter, everyone expects her to be the best cadet but she knows that she is far from it. As time goes on, and she still can't master the three rules, she becomes discouraged. It is not until the clowder is under threat and she is forced to make a journey to the city that she finds the skills within herself to lead others.

When the guardians charge her with a mission to help the leader of Dark Clowder she is confused and disappointed. After the harm Brokenear caused she had hoped that Dark Clowder was disbanded for good, but the Guardians insist that all four clowders need to be strong for the Stone to be strong. She dutifully tries to play her part but is filled with doubts about whether or not she is doing the right thing. It is not an easy journey, but along the way she discovers that although she is not good at being still, she has other skills to offer.

In the end she is forced to make hard choices. Does she follow in her father's footsteps or not?
