The 14-year-old Hyeon-wu is at the centre of this documentary which addresses labour relations and workers’ rights. Good Bye My Hero’s focus is on the effect of the ongoing union battles for better conditions within Korean factories on the family unit and specifically the family’s only son, Hyeon-wu. The patriarch of the family has been laid off due to his participation in protesting job losses from SsangYong Motors, and while the film documents his struggle through interviews and archive footage, it is narrated through intimate video interviews and diary excerpts by Hyeon-wu, as the teenager attempts to navigate the everyday issues related to growing up and fitting in at school with the uncertainty and social stigma of his father’s fight to be reinstated.
