Megatón ye-ye: The story of a music band from the sixties who wants to succeed in music in the style of Richard Lester films. There are two parallel plots: one is the love story between the singer Juan Erasmo 'Mochi' and Elena, a middle-class girl who has studied in Madrid and moved to Paris to work and to learn French. The other half of the film corresponds to 'Micky y Los Tonys', and especially to the wild Micky.
