The plot follows the friendship developed between two ballerinas dancing for a ballet company, as the two deal with work pressure and others' expectations.
Javier Ocaña of El País assessed that Dancing on Glass, featuring a "commendable physical and artistic work by Pedraza, and a formidable solidity in Martínez and Baglivi", is a "more than appreciable third film by a director still in his beginnings who, perhaps, has been overwhelmed by ambition in an excessively bizarre denouement".
