About

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.
Tropical scenery masks a claustrophobic nightmare where a group of friends faces the consequences of a fatal cover-up. Instead of a classic slasher, this reimagining leans into the psychological paranoia of being hunted in paradise.
