Flora, Flame, Marina and Sky are sisters and equipped with magical abilities: each of them is able to control one of the four elements. However, this only works as long as there is no disagreement or conflict between them. When the four discover a mysterious compass rose that activates a magical source, the wicked witch Glenda tries to sow discord among the sisters in order to weaken their magic and use the power of the source for herself. Mysterious events accumulate, and before they know it, Flora, Flame, Marina and Sky must resist several magical attacks. But also earthly challenges keep them on their toes: The four of them want to win an international singing competition in London, where they represent their school as the group "Sista Magic".
