The expression "Teenagers now a days" go way back, so there's nothing new about that. Scientific research and new technology has certainly brought us closer to what's going on in our brain during our teen years. But will it change anything?—Walther Jensen and Jesper Eugen Olsen

Adult Under Construction Wild, courageous, tired, hopeful, stubborn, rebel, sensitive. That's how we know them, the teenagers. But why are they overwhelmed by intense emotions and throwing themselves into fierce experiments? And what is going on in the human brain when it hits the teenage age? In this documentary, we meet a number of the world's leading brain researchers and get the explanation why we are going through so much on our way to becoming adults.
