The story begins in 1968 Spain with Esteban Guerra, an ambitious executive at Televisión Española, who is tasked with securing a victory for Spain at the Eurovision Song Contest. Esteban teams up with Artur Kaps, an eccentric music producer, to find the right song and artist to represent Spain. Their initial plan involves Joan Manuel Serrat, a popular singer, who is chosen to perform the song "La, la, la" at Eurovision.

As preparations advance, Joan Manuel Serrat insists on singing the song in Catalan, his native language, which causes political tension given the Franco regime's restrictions on regional languages. This disagreement leads to Serrat's withdrawal from the contest. Esteban and Artur must quickly find a replacement to keep Spain's hopes alive.

Massiel, a young and relatively unknown singer, is selected to replace Serrat. Despite initial doubts about her ability to carry the contest, Massiel commits fully to the challenge. She works intensively with Artur and Esteban to perfect her performance of "La, la, la," adapting the song to suit her style and the contest's demands.

Massiel travels to London for the Eurovision Song Contest, where she faces stiff competition and the pressure of representing Spain under the watchful eyes of the Francoist regime. During rehearsals, she encounters various challenges, including technical difficulties and the intimidating presence of other contestants.

On the night of the contest, Massiel delivers a charismatic and energetic performance of "La, la, la," captivating the audience and judges. Her rendition is marked by a confident stage presence and a catchy, upbeat rhythm that contrasts with the more traditional entries.

After the performances, the voting process unfolds with suspense.

This win marks Spain's first triumph at Eurovision and becomes a significant cultural moment.
