For college student Amelia "Amy" Clark, her 23rd birthday is supposed to be the party of a lifetime. She invites her friends to a massive beachside mansion on a secluded island, surrounded by music, drinks, and the ocean. For one night, Amy wants everyone to forget their problems and celebrate. But when the lights begin to malfunction, the party takes a terrifying turn. The mansion is plunged into darkness by a strobe-filled blackout, and when Amy and the guests attempt to leave, they discover the doors have been locked from the outside. Trapped with no way to call for help, they realize someone planned this. Someone inside the mansion wants them there. As a masked killer begins hunting them through the house, Amy must uncover the truth before everyone she invited becomes another victim. Because this isn't just a birthday party anymore. It's a game. And they must figure out who among them is capable of murder.

Seven years have passed since the nightmare of hitting a man destroyed her life and Maya thought she had finally escaped the darkness that followed her since that summer. Now living back in her hometown of Hollow Cove, Maya has built the life she always wanted. Married to Brody Cage and raising their young son, Michael, she has convinced herself that the past no longer controls her. With her closest friend Taryn back in her life after a difficult few years, Maya believes she can finally move forward and leave the secrets of her past behind. But Hollow Cove has a long memory. When a new wave of brutal murders begins targeting the people closest to Maya, the message left behind is one she hoped she would never see again: "I'll Always Know What You Did Last Summer." As the bodies pile up and old wounds are reopened, Maya is forced to confront the truth she has spent years trying to bury. The people around her begin questioning what really happened during those deadly summers, and every secret she fought to protect threatens to destroy everything she has built. With her family in danger and the past closing in, Maya must uncover who is behind the Fisherman's return before the person hunting her takes away the one thing she has left to lose. Because some secrets never stay buried. And some people never forget.

It was supposed to be the perfect night. The last summer party before life began to change. College applications, real relationships, and the looming pressure of adulthood - none of it mattered for one fleeting night on the beach. Bonfires blazed, music thumped, secrets stirred, and for a few hours, everything felt endless. Until it wasn't. A hit. A scream. A body. And a decision that would change everything. Maya, Jace, Taryn, Zane, and Y/N made a pact: forget what happened. No cops, no confessions, no guilt. They swore it never happened and promised to protect one another - even as it quietly shattered them from the inside out. Now, one year later, the summer sun has returned to their coastal town... and so has the past. When each of them receives an anonymous message reading "I know what you did last summer." what started as a shaky friendship quickly fractures under fear and suspicion. Someone is stalking them, watching their every move, recreating pieces of that night with unnerving precision. And when the threats turn to violence, the group is forced to confront not only what they've done - but who among them might be hiding even more. In a town where everyone's wearing a mask, trust becomes a weapon... and survival means facing a truth they swore they'd take to the grave.

One year after the massacre that changed everything, Maya is still trying to survive what she can't escape. Haunted by guilt, loss, and the decision to give up her newborn child, Maya hopes distance might finally quiet the past. When she and her best friend Taryn travel to Hawaii for what should be a fresh start, it feels like a chance to breathe again. But paradise doesn't stay safe for long. A violent storm traps them inside a luxury resort, cutting them off from the outside world. Then a message appears-one that shouldn't exist anymore: "I still know what you did last summer." Soon after, the killings begin again. Maya is certain Y/N has returned to finish what he started. Taryn refuses to believe it, convinced someone is staging a cruel imitation of past horrors. As suspicion spreads and bodies begin to fall, the group is forced into a desperate fight for survival-where no one can be trusted and nowhere is safe. Because whatever is stalking them in the storm isn't just repeating history... It remembers everything.
