"On the Road" tells the provocative story of Sal Paradise (Sam Riley), a young writer whose life is shaken and ultimately redefined by the arrival of Dean Moriarty (Garrett Hedlund), a free-spirited, fearless, fast talking Westerner, and his girl, Marylou (Kristen Stewart). Together, Sal and Dean travel cross-country in a quest for freedom from the conformity and conservatism engulfing them, in search of the unknown, themselves, and the pursuit of �it� -- the pure essence of experience. Seeking unchartered terrain and the last American frontier, the duo encounter an eclectic mix of men and women -- Bull (Viggo Mortensen), Camille (Kirsten Dunst), Carlo (Tom Sturridge), Jane (Amy Adams), Terry (Alice Braga), and Galat�a (Elisabeth Moss) � each adding meaning to their desire for a new way of life.
