Arianna Johnson and her twin brother, Mason Johnson, prepare for their summer stay at their family’s beach house in Southern California. They have grown up with Brady Lancaster and Cameron, whose parents were college friends with the Johnsons’ parents. Chase Harper joined their group when he moved into the neighborhood, immediately after which Arianna fell in love with him. Cameron knows about her feelings, but Arianna hasn’t acted on them because Mason is overprotective. He’s also been upset since their friend Payton’s boyfriend, Deaton, died in a car crash a few weeks prior.

The friends pile into the car and drive to the beach house. Their parents bought it years ago and are now giving it to their kids so that they can stay close after graduation. In a few months, they’re all starting college at Avix University, where the boys will play football. On the way, Cameron exclaims about the upcoming trip.
