Andres and Luis are two young taxi drivers eager to succeed. The first one sings and the other composes songs, and together they intend to record an album to finally jump to fame. They have it all planned. Taking advantage of a visit to the city of the famous singer Silvia, Luis tries to gain the confidence of her manager and, in this way, be directly launched to fame.

Bruno and Micky are two young people who abandon their studies to dedicate themselves to song. When Bruno meets Mayte and becomes a fashionable singer, he forgets about his closest friends. But success is short-lived ... One of the most delirious manifestations that Spanish cinema saw of the 'ye-yé' hatching, with an absolutely priceless Micky, half-self-interpreting, like Bruno Lomas and Massiel. The story revolves around the desire to succeed that drives the trio, as well as the romantic relationships established between them. Seen today, it must be as delicious as it is moving, especially considering that it premiered a year before Massiel caused a national earthquake by winning at the Eurovision Song Contest with the famous "La, la, la".
