Check out this link. There is a video of the movie trailer there. The movie deals with the NCAA and amatuer athletes, CTE and the long term affects from concussions. I've had the opportunity to view the entire movie. Very though provoking. There will be an screening in the Twin Cities area sometime in April. Not sure of the date yet.
