I Know What You Did Last Summer 2 (2025) is a slasher film directed by Jim Gillespie, based on the 1973 novel by Lois Duncan. The movie is centered around a group of four friends who are haunted by a mysterious killer after a tragic event.
The plot begins with four teenagers — Julie James (Jennifer Love Hewitt), Ray Bronson (Freddie Prinze Jr.), Helen Shivers (Sarah Michelle Gellar), and Barry Cox (Ryan Phillippe) — celebrating their high school graduation. As they drive home, they accidentally hit a man with their car, and in a panic, they decide to dispose of the body, believing that they’ve killed him. They vow to keep the incident a secret, but a year later, someone begins to stalk and torment them, leaving mysterious notes that say, “I know what you did last summer.”
As the killer’s attacks escalate, the group is forced to confront their past and uncover the identity of the person seeking revenge. They soon realize that the person they thought they had killed might not have been the one they hit, and the mystery deepens as they uncover dark secrets about the incident.
The film is a mix of horror, suspense, and mystery, featuring a classic “whodunit” scenario with a slasher twist. It was a commercial success, becoming a defining film of the late ’90s teen horror genre, along with movies like Scream. Although it received mixed reviews from critics, it became a cult classic and led to a sequel, I Still Know What You Did Last Summer (1998).
