An unexpected series of events turns everyday store clerk Harley (Alex Sharp) into a wanted man and, even more unexpectedly, he finds himself on the run with the girl of his dreams (Analeigh Tipton). FBI Agent McFadden (Maria Bello) is determined to crush him and wants to teach her rookie partner (Karan Soni) how it's done. But while the agents pursue their culprit, our hero has loftier pursuits. He kidnaps his Vietnam vet grandfather (Jeremy Irons) to reunite him with the love of his life, picks up a try-hard beatnik hitchhiker (Edi Gathegi) with a secret of his own, and against all common sense, follows a roadside attractions map with a mysterious history.
