Nothing much happens in Sycamore, the small village where Clara lives - at least, that's how it looks. She loves eating ripe mangoes fallen from trees, running outside in the rainy season and escaping to her secret hideout with her best friend Gaynah. There's only one problem - she can't remember anything that happened last summer. When a quirky girl called Rudy arrives from England, everything starts to change. Gaynah stops acting like a best friend, while Rudy and Clara roam across the island and uncover an old family secret. As the summer reaches its peak and the island storms begin, Clara's memory starts to return and she must finally face the truth of what happened last year.
