"Dancing Showdown" is also known as "Street Dance 3D". The film is hailed as the first 3D film in the UK. The life of the young and beautiful dancer Carly (Nichola Burley) is at its peak. She has a charming and handsome boyfriend Jay. The dance group they joined has just entered the finals of the British Street Dance Championship, but Jay suddenly leaves Carly and the dance group at this critical moment. The cruel reality not only breaks Carly's heart, but also puts the dreams of other members in jeopardy. The principal of the ballet school, Helena (Charlotte Rampling), is moved by the dancing skills and enthusiasm of Carly and her dance group and lends a hand. They can practice dancing in the luxurious dance studio of the ballet academy, but they have to train with ballet dancers to get free training venues. Noble ballet and grassroots street dance, these two unrelated and somewhat irreconcilable dance forms have come together like this. When ballet and street dance, two dances that are diametrically opposed, confront each other head-on, the conflict begins. Can Carly's dream of becoming a champion finally come true?
