It stars Jennifer Love Hewitt, Freddie Prinze Jr. and Muse Watson, who reprise their role from the first film, while Brandy, Mekhi Phifer, Bill Cobbs, Matthew Settle, Jennifer Esposito, Jack Black, Jeffrey Combs, and John Hawkes also star.

One year after the brutal murders of her friends Helen Shivers and Barry Cox by the vengeful fisherman Ben Willis, Julie James is attending summer classes in Boston, but suffers from nightmares of the incident.

Julie's roommate, Karla Wilson, receives a phone call from a local radio station and wins a vacation for four to The Bahamas.

That evening, Ray and his co-worker, Dave, drive to Boston to surprise Julie, but stop due to a body in the middle of the road.

That evening at the hotel's bar, Julie is singing karaoke when the words "I still know what you did last summer" roll on-screen.

Horrified, she informs them, but Darick's body is missing; Mr. Brooks, the hotel manager, refuses to believe her story.

The next day, the group finds Olga, Titus, and Mr. Brooks murdered and the two-way radio, their only way of contact, destroyed.

Julie and Nancy rescue Karla and run to the storm cellar, where they find Ben's victims.

In 1997, director Mike Mendez pitched a sequel to I Know What You Did Last Summer that would have brought back Jennifer Love Hewitt and Freddie Prinze, Jr. in a college setting.

[6] The following February, British filmmaker Danny Cannon was announced as director, unrelated to Mendez's idea.

[9] In a 2018 interview, writer Trey Callaway revealed that he was asked by Mandalay Pictures if he was interested in penning the script for the sequel.

[10] In order to capitalize on the success of the first movie, the studio was eager to get production underway, with filming starting around six months after Callaway sold his pitch.

The site's critical consensus reads, "Boring, predictable and bereft of thrills or chills, I Still Know What You Did Last Summer is exactly the kind of rehash that gives horror sequels a bad name.

"[12] On Metacritic, the film has a weighted average score of 21 out of 100, based on 19 critics, indicating "generally unfavorable reviews".

[14][better source needed] Leonard Klady of Variety said: "Purists will find the pic's obviousness disappointing, but there's no question that the film delivers a sufficient shock quotient to satisfy its youthful target audience.

In February 2023, a new legacy sequel was announced to be in development with Hewitt and Prinze Jr. in talks to star, and Jennifer Kaytin Robinson directing from a script by Leah McKendrick.
