The two-act play "Les Belles-sœurs" by Canadian writer Michel Tremblay premiered in 1968 at the Théâtre du Rideau Vert in Montreal, Canada. Many consider it to have had a profound impact on Canadian culture, as it was one of the first times "joual" was seen on a national stage. The play follows a working-class woman named Germaine in Montréal, Québec, Canada. After winning a million trading stamps, she invites her friends over to help paste them into booklets to redeem them. But Germaine is unsuspecting of her jealous friends who are envious of her winnings. The fact that the play was originally written in "joual" is very important to the socio-linguistic aspect of the women. The characters all come from the working class and for the most part, speak in "joual", which at the time was not seen on the main stage. The play was cited at the time as a "radical element among Quebec critics as the dawn of a new era of liberation, both political and aesthetic".
