The group decides to keep their involvement a secret, swearing never to discuss the incident again.
However, one year later, they each receive a mysterious note reading, “I know what you did last summer,” and find themselves being stalked by a vengeful figure.
The suspenseful plot follows the characters as they try to uncover the identity of their stalker and face the consequences of their actions.
Film Summary
The 1997 film adaptation of ‘I Know What You Did Last Summer’ maintains the core plot of Duncan’s novel.
After a night of partying, four high school friends – Julie, Helen, Barry, and Ray – accidentally hit a pedestrian with their car and they decide to dump the body into the ocean to avoid getting caught.
One year later, the friends are targeted by a mysterious figure who seems to know their secret.
As they struggle to stay alive, they must also confront the truth about what happened on that fateful night.
Key differences between the book and film
While the basic premise of the book and film remains the same, there are several notable differences between the two.
One of the most significant changes is the addition of the character Benjamin Willis, the father of the young boy killed in the accident, who becomes the primary antagonist in the film.
In the novel, the antagonist is revealed to be Bud, David Gregg’s older brother.
Another difference is the setting: the book takes place in a small town in New Mexico, while the film is set in a coastal town in North Carolina.
Additionally, some of the characters’ names are changed, such as Helen Rivers becoming Helen Shivers and Ray Bronson turning into Ray Bronson.
The film also introduces a romantic subplot between Julie and Ray, which is not present in the book.
Lastly, the film’s climax is much more action-packed than the novel’s, with the characters engaging in a life-or-death struggle with the antagonist.
In contrast, the book’s climax is more focused on the psychological aspects of the characters confronting their past actions.
