A bandit, a garbage collector, a girl who works, a boy who doesn't want to work, a girl who emigrates and a ghost looking for company. These and other characters make up the fantastic world that we discover among the trees of a forest. Opposite the world of the poor, the world of the rich: the lords of the pazo, the vacationers from Madrid, and the mistress who exploits the children because her hopeless bachelorhood has exacerbated her love of money. Among them all, the train that runs along the forest roads, which brings and takes passengers and is the only link that unites and disunites them.
