Sometimes I envy people who don't have children, declares the main character's mother in the most poignant scene of the award-winning Sister of Mine. This statement is made amidst a peculiar domestic conflict involving Zuzia, a drug-addicted teenager, her older brother Mariusz (the film's director), and their parents. Despite the chaos of harsh words, desperate gestures, and shaky alliances, there is a glimmer of hope for peace talks. This hope is largely due to the presence of the camera, which becomes a tool for painful yet cleansing self-reflection for each of the characters.
