An interconnected group of recent high school grads navigates through personal issues while enjoying their "last summer" before moving on to college.

Griffin Hourigan, a prep school grad, is preparing to enter Columbia University, thanks to nepotism (his father), despite wanting to attend Berklee College of Music.

Erin and Alec, a high school power couple for two years, agree to break up before leaving for college.

Though they plan to be respectful even while apart, Erin is shocked when Alec quickly falls under the spell of Paige Wilcox, a popular, vapid classmate who immediately snatches him up.

Alec breaks up with dull-witted Paige and unsuccessfully tries to win Erin back, becoming jealous when he learns of her relationship with Ricky.

Some time later, Alec comes to her send off party; they decide to be friends again, moments before kissing and possibly renewing their relationship.

Disappointed, she decides to pursue her last choice, waitlisted option while taking up a job as a nanny to precocious child actress, Lilah.

Waiting for an audition on AGT that could help launch a 'career,' they simultaneously decide to skip it and go to the beach, as Lilah desires.

Though eventually accepted by her safety school, Audrey, when told initially she would be on academic probation, excluding her from much of student life on campus, she declines.

After attempting to hook up with a virginal Christian girl, he thinks he is making progress with another at a party, only to discover his wishlist went viral, and no one will sleep with him now.

Discussing the disappointment with Alec, Foster admits that, due to his busy schedule in school, he is actually a virgin; the wishlist was his attempt to make up for lost time.
