Enrique (Enrique del Pozo) and Ana (Ana Anguita) are two popular singers-turned-actors in this adventure story of the evil Baron Von Nekrus and his minions who are intent on becoming masters of the world, and the two youngsters who are out to stop him. Ana's good-hearted grandfather has been imprisoned by the Baron so he can extract his scientific knowledge, and now Ana and Enrique have joined a musical group called the Coconuts to go on tour and in that guise to infiltrate the Baron's headquarters. They are accompanied by their nanny and tutor Castaneta (Amparo Soler Leal) and an African explorer named Stanley (José Lifante). Against all odds, they get into the Baron's stronghold and free the grandfather -- but it does look very much like the nasty Baron will escape to continue with his nefarious plots in a sequel.
