Rosa Rosae (1993)

Rosa (Ana Belén) and Rosae (María Barranco) are two former schoolmates reunited after a long time. One is an unsatisfied bourgeois despite her affluent life. The other is a non-materialist bohemian who practices esotericism.
In the forty-second minute Ana Belén and María Barranco enter a room full of naked men and women who are dancing. Ana and María are also naked. In a long sequence the two naked actresses douse themselves with red paint and dance with everyone else.
