The James family (Sienna, Luca, and their parents) travel to Hawaii for a month-long vacation, reuniting with the Hayes (Flint, Lila, Harper, and their parents). The two families, connected since high school, clash and bond in equal measure. Flint, pride of the Hayes surfing team, is competitive with Sienna, whom he calls a "recreational brat" for her casual skill. She mocks his arrogance, dubbing him "Mr. Perfect." Meanwhile, Luca and Lila share a flirtatious subplot, and Harper immediately adopts Sienna as her "bestest big sister."
The tension escalates when Flint suffers a brutal wipeout during a competition, shattering his arm and ending his season. His career hangs in the balance, and his physical therapist insists on intensive rehab. Desperate, Flint issues a challenge to Sienna: "Train me, and I'll admit you're the better surfer... even if just for once." Sienna agrees, partly to spite him, partly because she's curious about the brooding boy beneath his cocky shell.
