The artist Res Benito is preparing a huge mural on the orgasm, which, according to him, is the origin of song, for the Liceu theatre. Three barbers give him the hair he needs for his work. Meanwhile Rubén Montesinos, who works with the homeless, is given the task of searching for Lídia Moja, sister of Ricard, who disappeared in India over thirty years ago.
Thus begins a story built like a set of gears that move the world, spin it around, make the poor rich and the rich a little less rich. A novel without goodies or baddies, full of comedy and drama, in which everyone is forced to change and, if possible, to improve.
