High school classmates Sutter (Teller) and Aimee (Woodley) are polar opposites. After a night of partying, Sutter wakes up drunk and confused on a stranger's yard — but not just any stranger. Unlike Sutter, Aimee has never been in a relationship, doesn't party, and has her eyes set on college. The last thing she anticipated was to wake up and find Sutter hungover on her lawn. The more time these two spend together, the more they can't help but fall magically in love.
