Why is Marte the Chicken so unhappy, where do the blue footsteps come from, and why doesn't the radio work? Mysterious things are happening at Sesam Stasjon.
Max Mekker, Alfa and Bjarne Betjent count the days until Leonora returns from her journey to Milan, so she can solve the mystery. While they're waiting, they follow the clues to the circus, the zoo, Viktor's garage and Jensen's shop.
