The highly anticipated follow-up to A Girl at My Door (2014), Jung’s Cannes Critics’ Week closer is a darkly compelling portrait of exploitation, bureaucracy and accountability. Inspired by the real-life suicide of a high school student, the film’s first half focuses on the cheerful, dance-loving Sohee (impressive newcomer Kim Si-eun), an intern at a call centre who soon realises she is trapped in a toxic environment. The second follows the investigation by police detective Yoo-jin (Doona Bae, Sympathy for Mr Vengeance, The Host) into Sohee’s death. Who should be held accountable, and how can we prevent someone else from becoming the next Sohee? Jung’s film fearlessly searches for answers, while uncovering the uncomfortable truth behind the tragedy.
