Dibi-dubi-dubà Maria's grandfather's old amusement park is about to become a theme park dedicated to technology and virtual reality. Before the works begin, the workers of the new park are in charge of emptying the old warehouses, which are full of boxes that still preserve the remains of the old fair. Maria doesn't want to know anything about what's inside the boxes; it hurts too much to remember the past. When one of the workers discovers the fantastic world hidden inside these boxes, she decides to travel to the old park using values that never go out of style: imagination, music and memories. Will they be able to revive the old fair and integrate the past into the present?
