The first season of The Summer I Turned Pretty introduced viewers to the world of Belly and her annual summer trips to Cousins Beach, where she and her family would stay at Susannah’s beach house with her and her two sons. The children have all grown up together, but in the summer just before Belly turns 16, she has blossomed and found herself in a burgeoning love triangle with Susannah’s two sons Conrad and Jeremiah.

Much of the season follows Belly as she navigates her complicated relationships between Conrad and Jeremiah, while also preparing for a debutante ball in Cousins Beach. Jeremiah is supposed to be her date, but when he is unavailable, Conrad steps in for Belly’s final dance.

After examining her feelings for both Conrad and Jeremiah, brothers, Belly eventually decides she wants to be with her lifelong crush Conrad. But things aren’t that simple, as the teens all soon learn that Susannah is dying of cancer, and wanted this final beach trip to try and have one final, perfect summer.

Season 1 ends with Belly and Conrad together, with Susannah attempting an experimental cancer treatment as she agrees to not give up hope in the wake of her illness.

Belly is grief-stricken and heartbroken, as she and Conrad have since broken up. Jeremiah continues to harbor feelings for Belly that have turned to resentment at times in the year since the events of the previous season. But when Conrad goes missing from college, Belly and Jeremiah reconnect to find him—only to realize he’s returned to Cousins Beach in an effort to save the beach house, which is on the verge of being sold by Susannah’s estranged sister Julia.

Belly’s brother Steven and her best friend Taylor soon join them, as the teens look to find ways to potentially stop Aunt Julia from selling the beach house, and to reconnect with one another during the process.

Following some discussion with their father, Conrad and Jeremiah are able to convince him to move some assets around and purchase the house to keep it in the family—preserving their summer home and the memories of Susannah.
