At the end of Season 2, Belly chose Jeremiah and let go of her past with Conrad. But in Season 3, that past shows up again. According to the official logline, “Her future seems set, until some core-shaking events bring her first love Conrad back into her life.”

Now, Belly is spending another summer in Cousins Beach after her junior year of college. She must face the same question: who really has her heart? “Now on the brink of adulthood, Belly finds herself at a crossroads and must decide which brother has her heart. Summer will never be the same,” Prime Video teases.
