Cecilia is a middle class sociology lecturer; separated from her partner, she raises her young son, Juan, with assistance from Nebe, a working class woman who is employed to help Cecilia with housework and childcare. Late one night, in the midst of a storm, Kevin, Nebe’s adolescent son, knocks on her door in a state of considerable distress. Cecilia is too afraid to let him in. The next day, Kevin’s body is found in a river. A study in alienation, reminiscent at times of Lucrecia Martel’s The Headless Woman, A Common Crime explores the injustices of Argentine society, which manifest themselves in the growing gap between rich and poor, employees and employers.
