Just before he leaves for university, Hugo Wilkinson gets dumped by his girlfriend. Unfortunately, they'd planned on taking a romantic cross-country trip across America and the tickets are non-refundable--and in his girlfriend's name. He takes out an ad for another Margaret Campbell to take the trip with him. Margaret "Mae" Campbell sees the ad, and, fresh off a rejection for film school, decides to join Hugo, a complete stranger, on the trip. What starts as a simple, convenient trip for each to shake off their heartbreak turns into something more as they learn about each other and what it means to build a future.
