Kim Yuri’s ambitious and incredibly moving feature debut follows two girls’ tumultuous lives over three separate time frames, from ages 12 to 19. After Young-ha’s father abandons her, she continues living with her struggling mother and stepfather. Her cousin and best friend Mi-jin is similarly bounced around, and the two form an inseparable bond as they navigate the challenges of growing up with less-than-reliable adults as their caregivers. Sub-Zero Wind takes on myriad issues with refreshing candor as it subtly unfolds a complex cautionary tale of parents acting badly and children fighting the odds to survive on their own.
