A father and his three children embark on an uncertain cross country journey in this emotional coming of age drama starring Oscar-nominee John Hawkes. In the quiet pre-dawn hours of a New England morning, Tom (Hawkes) rouses nine-year old Nat (Ty Simpkins), 12-year-old Greta (Ryan Simpkins) and their older sister Caroline (Kendall Toole) and hurries the trio into his dilapidated station wagon. As their 3,000 mile trip to California gets under way, Tom talks dreamily of life on the West Coast while reassuring his kids that their mother isn't far behind. Meanwhile Caroline resents being torn away from her boyfriend back home, Greta holds her stuffed bunny Harrison tight, and Nat longs to experience the majesty of the Grand Canyon. With each mile they travel, however, Tom's mood seems to sour, and before long a trip that was at first merely difficult becomes downright dangerous.
