Dolezal posed as a woman with African-American heritage during her time as branch president of the NAACP in Spokane, Washington. Her white family eventually outed her.
In the just released trailer, Dolezal's biological son Franklin is highlighted talking about his mother's unfortunate interviews and how he is affected by them.
"This is gonna affect more than just your life...Trust me, it is going to bite me in the ass," says Franklin.
He also adds: "This book coming out and this documentary coming might just backfire, like everything else has backfired... I resent some of her choices and I resent some of the words she's spoken in interviews."
In past interviews, Dolezal denied being untruthful about who she is.
"The Rachel Divide" will be released on Netflix on April 27, 2018.
