The movie is based on a fair tale of a male named Christopher McCandless. It’s a tale of a male who was sensitive and loved freedom. He has seen enough of society and wants to run away into the wild to live freely and he chooses it over anything else which his career might have offered him after getting graduated from college. His two years of hitchhiking-roaming makes him have experiences more profound than most of us have in our entire lifetime. More information: harry potter 7 trailer
