Presentation for High School Students in an Alternative Program

I am doing a presentation on trauma to older high school students in an alternative program.  Had thought about showing Paper Tigers with follow up conversation.  I know there are other documentaries and perhaps even Ted Talks or YouTubes that would speak to their experiences. I am looking for suggestions.   These students live in an urban setting that oftentimes reeks of toxic stress.  Also, wold appreciate suggestions of icebreakers to use.  The groups will be small, lending the conversation to more interaction with one another as well as with myself, as facilitator.
