The premise

In a sun-soaked Hawaiian town with a mysterious past, a group of friends is left with a dark secret after a tragic accident. One year later, a member of the group receives a threatening message, and the friends now know that someone intends to make them pay for last summer.

Horror Vault's take

Set against the deceptively bright backdrop of a Hawaiian town, this series follows a tight-knit group of friends whose lives unravel after a devastating accident they choose to bury. A year on, an ominous message signals that someone knows exactly what happened — and justice, twisted or otherwise, is coming. Equal parts murder mystery and slasher, the show stretches its cat-and-mouse tension across a full season of escalating dread. Fans of the original film will find a reimagined story that leans into small-town secrets and ensemble paranoia.
