I Know What You Did Last Summer is a 2025 American slasher film that is the fourth installment in the I Know What You Did Last Summer franchise and a sequel to I Still Know What You Did Last Summer (1998). The film takes place 27 years after the Tower Bay murders in the second film, when another hook-wielding killer appears and begins targeting a group of friends one year after they covered up a car crash in which they killed someone. It was directed by Jennifer Kaytin Robinson, who co-wrote the screenplay with Sam Lansky from a story by Leah McKendrick and Robinson. The film stars Madelyn Cline, Chase Sui Wonders, Jonah Hauer-King, Tyriq Withers, Sarah Pidgeon, Billy Campbell, Gabbriette Bechtel, and Austin Nichols, with Freddie Prinze Jr., and Jennifer Love Hewitt reprising their roles as Ray Bronson and Julie James from the first two films.
When five friends inadvertently cause a deadly car accident, they cover up their involvement and make 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.
