Hannah spends her vacation pining for Jackson, her best friend’s older brother, while trying to hide her ten‑year‑old crush. She and Emmy enjoy the luxury of the resort, though Hannah feels lingering awkwardness with Jackson following a mysterious incident over winter break.
Emmy suggests Hannah needs a “rebound crush” to clear her mind before college. While swimming, Hannah meets Ben, a handsome and wealthy boy on a paddleboard who immediately charms Emmy.
Jackson watches Hannah from the shore, maintaining a serious and distant demeanor. A massive wave suddenly wipes Hannah out, and Jackson helps her up, teasing her about her lack of ocean awareness. He compares the ocean’s unpredictability to his sister, then walks away, leaving Hannah frustrated by his behavior.

Chapter 2: The Proposal
Ben becomes a fixture in the girls’ vacation, paying for expensive activities like jet skiing and massages. During a trip to a local market, Ben buys Emmy a turquoise necklace and buys himself a gold lighter.
He proposes chartering a private sailboat for their last full day, an idea Emmy enthusiastically supports. Hannah is skeptical of Ben’s “Moneybags” persona but appreciates his inclusion of her in the plans.
Emmy’s parents initially hesitate because of an approaching storm, but they agree on the condition that Jackson goes along to supervise. Jackson is reluctant and clearly dislikes Ben, but he agrees to go for Hannah’s sake. He tells Hannah he doesn’t want to “take anything else” from her. Hannah worries about being trapped on a small boat with her crush.
Key Moment: Jackson agrees to join the boat trip specifically to ensure Hannah’s safety.
New Information: Ben’s father and Emmy’s parents attended the same college, which helps Ben gain the parents’ trust.
Chapter 3: Ignoring the Warnings
On the morning of the trip, the sky is dark and ominous, making Jackson and Hannah doubt the safety of the excursion. Ben insists the captain said they are “good to go,” and they head to the marina.
They discover that all professional tours are canceled due to the storm, yet Ben has found a man named Keith willing to take them for a thousand dollars. Keith operates a worn sailboat named The Be‑Yacht‑Ch and claims the professional tours are just overly cautious.
Jackson tries to force Emmy off the boat, but she refuses, choosing to stay with Ben. Feeling obligated to protect Emmy, Jackson and Hannah both board the vessel. As they leave the marina, Keith blasts loud music and demonstrates a relaxed attitude toward safety. Hannah notices a large “NICKELBACK” tattoo on Keith’s chest and realizes they are in for a strange day.

Ben then shocks Hannah by inviting himself on Emmy’s solo world tour, and Emmy immediately agrees. Hannah confronts Emmy about trusting a stranger so quickly, leading to a heated argument.
