Soledad Pastorutti and his friend Larguirucho go on a tour through Argentina while evading the wrong deeds of Cachavacha, the witch.

The witch Cachavacha is envious of the voice of Soledad, who is loved by all children. Cachavacha will do anything to prevent Soledad from continuing to sing, so she asks the help of the evil Professor Neurus and his longtime lackeys Pucho and Serrucho. But Soledad is not alone in this fight, counting on the support of her friend, Larguirucho.—exe_malaga93
