Best friends Bénédicte, a pianist, and Morgane, an opera singer, make an eclectic musical duo. Performing in old-age homes and obsolete shopping centres, the audiences for “Les Bonnes Arias” are often not too attentive, and the duo find themselves in absurd situations. It should be noted that the operas they present are out of the ordinary; they also mix in theatre and wild costumes! While preparing for a competition “My First Springboard for the Emerging Arts Scene of Beloeil”, their strong friendship is shaken by disappointment and betrayal.
