I Know What You Did Last Summer (franchise)

In 1973, Lois Duncan's I Know What You Did Last Summer was published. It was republished as a tie-in to the film in 1997 and once again in 2018 with some of its content modernized. The film adaptation reenvisioned the story of the novel as a violent slasher film, as opposed to the slow-burn mystery nature of the novel.

After an accident on a winding road, four teens make the fatal mistake of dumping their victim's body into the sea. But exactly one year later, a mysterious fisherman begins stalking the friends.

The murderous fisherman with a hook stalks the two surviving teens, Julie James and Ray Bronson who left him for dead. Despite Julie's warnings, her friends do not believe her until it is too late, and the fisherman begins a second murder spree at a posh island resort in the Bahamas.

A group of teenagers in Colorado find themselves being stalked and killed one by one by a mysterious figure with a hook, exactly one year after they covered up a friend's accidental death.
