The thing about secrets, is that no matter how hard you try to bury them, they have a way of resurfacing. The long-awaited sequel to Jim Gillespie’s 1997 slasher of the same name has dropped a chilling new trailer for the 2025 sequel to I Know What You Did Last Summer. The secrets have returned and they are angry, bloody, and armed with a hook. The film is the fourth installment in the “I Know What You Did Last Summer” franchise and will serve as a direct sequel to the 1997 original, in which a group of friends are haunted by a hook-handed killer one year after they killed a man in a hit-and-run accident.
This long-awaited continuation drips with tension and nostalgia. It aptly blends the eerie charm of the original 1997 classic with the slick menace of modern horror. Jennifer Love Hewitt returns as Julie James still haunted by that fateful night with Freddie Prinze Jr. as Ray Bronson in the legacy sequel. They are accompanied by a new generation of guilt-ridden teens that have stumbled into the same deadly cycle. The trailer wastes no time reminding us that the past has a way of returning beyond the grave that you thought had safely housed it.
The trailer focuses on five friends (Madelyn Cline, Chase Sui Wonders, Jonah Hauer-King, Tyriq Withers and Sarah Pidgeon) who inadvertently cause a deadly car accident and form a pact to keep it a secret rather than face the consequences. A year later, their past comes back to haunt them and they’re forced to confront a horrifying truth. Someone knows what they did last summer and is hell-bent on revenge. As one by one the friends are stalked by a killer, they discover this has happened before, and they turn to two survivors of the legendary Southport Massacre of 1997 for help.
The movie is directed by Jennifer Kaytin Robinson and co-written by Robinson and Sam Lansky, following an initial draft from Robinson and Leah McKendrick and based on characters by Lois Duncan. The trailer unspools like a nightmare: shadowy coastal towns, flickering bonfires, whispers in the dark, and the unmistakable clank of a fisherman’s hook dragging across pavement. The trailer suggests deeper emotional stakes, but whether it delivers a truly clever continuation or just sharp kills in pretty packaging remains to be seen.
