Renee Firestone at USC on Jan 15 (Charlie Magovern/Neon Tommy)

Renee Firestone didn’t know how to sew a gown in 1944, but she didn’t tell the Nazi officers at Auschwitz that.

It has been nearly 70 years since the infamous death camp was liberated, and Firestone never did have to finish the dress she was ordered to create as a prisoner.

She did go on to be a successful fashion designer after the war ended, however, and she recounts her story of survival in CNN’s latest documentary, 'Voices of Auschwitz'. Hosted by Wolf Blitzer, the documentary premiered at the University of Southern California, presented by USC’s Shoah Foundation, and the Annenberg School for Communication and Journalism, on Jan 15.

The six-part documentary features the stories of four Holocaust survivors, still living today. Viewers embark on the personal journeys of four people who have one thing in common: each survived the most notorious hellhole — and systematic genocide — of the century.

Firestone stayed after the premiere to speak with Neon Tommy. Firestone discussed the extensive public speaking she has conducted throughout her life, touring the country and spreading messages of acceptance and communication to young people.

Despite the communication, Firestone is still worried about the future.

"I talk to young people and they say they hear me, but nothing has changed. We are still killing each other," Firestone said.

"When I see young people sitting across from each other playing on machines, I feel hopeless," Firestone said. "How are we supposed [to solve problems] if we don't talk to each other?"

Renee's story can be viewed on 'Voices of Auschwitz', premiering on Jan 26 at 9PM EST, on CNN.
