Nina and the Hedgehog's Secret

Every night, to counter the dreariness of his days toiling in a factory, Nina’s father tells bedtime stories. A little hedgehog is the unlikely hero of his tales. One day, the father is fired from the factory. When it’s time to be tucked in, Nina finds herself alone, eager to hear the next chapter in the small animal’s adventures. With her best friend Mehdi, the girl goes off in search of a treasure hidden somewhere in the factory where her father used to work. What if the little hedgehog could also help in the quest?
