Directed by Giada Colagrande, Aprimi II Cuore follows the obsessive and sometimes incestuous relationship between sisters Caterina (Colagrande) and Maria (Natalie Cristiani). Caterina, 17-years-old and shy, loves the arts and takes comfort in listening to music while her sister, a prostitute, entertains her nightly host of clients. Living in the apartment becomes harder with each passing day, as Maria is only allowed to leave to go to dance class. Despite Marias efforts, Caterina falls for her dance teacher, Giovanni (Claudio Botosso), and series of perverse situations present themselves as the siblings compete for his attention. ~ Tracie Cooper, All Movie Guide
