1999. Teenager Tomás is clearly too much of a handful for his mother so she packs him off to stay with his big brother who is studying in Mexico City. Fede lives with Santos in a concrete pre-fab apartment building. They are currently striking against the strike which their fellow-students are organizing at the Universidad Nacional Autónoma de México.
Tomás has brought a cassette along with him -- the tape is part of his father's legacy and contains the music of Epigmenio Cruz. They say he could have saved Mexico's rock music scene from ruin. When the trio learns that their idol is in hospital fading fast, they set off in their broken down car to pay their last respects to this one-time rock star.
