Documentary filmmaker and father Iain Cunningham knows all about the myths we like to tell ourselves about family. But he knows just as much about the details our parents sometimes leave out, and the impact those family secrets can have on children who never learn the truth. Cunningham’s mother Irene passed away when he was just three years old, and his family rarely spoke or shared memories of her for decades, leaving Iain to wonder what kind of person his mother was, and what exactly led to her death.
