Filmmaker Ida Eva Zielinska showcases The Donald Marshall Jr. Story, a 2009 documentary that tells the facts of how Marshall was wrongly convicted of murder. From the filmmaker:

"Donald Marshall Jr., a Mi’kmaq from Nova Scotia, was destined to succeed his father as Chief. Instead, he was convicted of murder at age 17, and spent 11 years in jail. One of Canada’s highest profile wrongful conviction cases, it revealed many flaws and systemic racism in the justice system. This documentary marked the first time Donald agreed to tell his own story on camera. He died at age 55, one year later."
