Tuchi longs to join in and play with the school's mariachi band, but it's the 1970s and in her community, mariachi is only for the boys. Still she hopes--and wishes to play in the mariachi.
Tuchi finds her Nana's guitarrón and, in secret, Nana teaches TYuchi to play. The music rumbles inside Tuchi like desert thunder. Will Tuchi be ready for the big audition? And will Seńora Luna help Tuchi make her wish come true?
