Cadence devises a plan to trigger her latent memories of the final hours before her traumatic accident, but she can’t do it alone – she must convince the reluctant Johnny, Mirren, and Gat to help her, even if it means risking everything.
More uncertain than ever, Cadence reluctantly joins Harris on an excursion, triggering memories of their final confrontation in Summer 16. During a tense family dinner, The Liars confront their mothers about family secrets.
Unable to continue keeping secrets from her, Gat finally opens up to Cadence about his perspective on the island – one that doesn’t always reflect the fairy-tale nostalgia of her own experience.
Unsettled by a series of painful memories, Cadence tries to enjoy what’s left of her summer – even if it means distracting herself with a potentially dangerous stunt.
As the Sinclairs prepare for a quiet Fourth of July, Cadence investigates one of The Liars, uncovering memories of last year's crowded celebration. While the Sinclair sisters vied for their father's approval, The Liars navigated their romantic lives and Ed surprised Carrie.
Having remembered a family tragedy, Cadence presses The Liars for answers. Mirren reveals a crush gone awry, Johnny recalls an unwanted visitor, and Gat recounts their relationship's painful turn.
Following her mysterious accident, Cadence has suffered a year of illness, amnesia, and loneliness, having had no contact with The Liars. Returning to Beechwood for answers, she finds even her closest friends won't discuss the summer she can't remember.
Every summer, Cadence Sinclair cherishes her time with her cousins Mirren and Johnny and her best friend Gat on Beechwood Island. At sixteen, what begins as their usual summer of mischief transforms when Cadence and Gat fall in love, while adult tensions rise in her family.
