Three Texas teens find their lives spinning quickly out of control following the death of their father in this period drama set in 1974. Left in the care of their abusive mother after their father dies unexpectedly, the three close-knit siblings find their once-stable lives uprooted when their mother sends one away due to his autism. Convinced that he can set everything right if he can just track down his brother and find his way to their caring grandmother, the oldest sibling steals the keys to their father's station wagon, loads up his sister, and hits the open road. Along the way, each of the siblings starts to realize that the best things in life are all worth fighting for, no matter how hard the struggle may be.
