Jennifer Love Hewitt and Freddie Prinze Jr. return in new 'I Know What You Did Last Summer' sequel

Decades after starring in the 1997 original I Know What You Did Last Summer, Jennifer Love Hewitt and Freddie Prinze Jr. will return in the upcoming sequel this summer. The two starred in the OG slasher film as Julie James and Ray Bronson, respectively, and also returned to the roles in the 1998 sequel, I Still Know What You Did Last Summer.

The upcoming sequel will be the third time they play their respective roles, which audiences got the first glimpse of in the newly released trailer. The new movie introduces five new friends who will lean on the two survivors of the legendary 1997 Southport Massacre for help as they become the hunted of a killer.

Teasing her comeback in the slasher sequel, Jennifer Love Hewitt told People in an exclusive interview published on April 8, 2025, that there will be many nostalgic callbacks and easter eggs. She said:

"There's a lot of '90s in there, so get excited because the '90s are back again."

She also described the movie as a "really fun ride," further teasing that there will be plenty of twists and turns and that people won't expect anything that's coming.

Plot of the sequel explored

Released over two decades after the original movie, the plot of the I Know What You Did Last Summer sequel mirrors the OG horror film—a group of friends bound by a tragic accident find themselves being hunted by a killer. In the upcoming sequel, there will be five friends who caused a deadly accident. After covering it up, they agreed to keep it a secret instead of facing the consequences.

However, a year after the accident, the past and present collide after someone discovered what they did. Even worse, that person is hell-bent on revenge. The official synopsis of the sequel teases a bloodied, horrifying turn of events for each of them, which partly reads:

"As one by one the friends are stalked by the killer, they discover this has happened before, and they turn to two survivors of the legendary Southport Massacre of 1997 for help."

Is there a trailer for the I Know What You Did Last Summer sequel?

Sony Pictures released the first trailer of I Know What You Did Last Summer on Tuesday, April 22, 2025. It opens with Madelyn Cline's character preparing to take a bath. She uses a bath bomb that ominously makes the water in the tub look bloody. Meanwhile, a killer with a hook in one hand targets his boyfriend downstairs with a harpoon to the heart.

Cline's character thinks it's a gruesome manifestation of karma for what they did before. Meanwhile, the townspeople believe it's a series of senseless crimes, but according to Freddie Prinze Jr.'s character, as seen in the trailer, it wasn't the first time something like it happened in Southport. The camera then zooms into Elsa and Helen Shivers' tombs.

As thrilling music plays, the words "You're next" appear as the killer haunts the friends one by one. Jennifer Love Hewitt's character also appears at the end of the trailer and appears to have a hunch about why the friends are being targeted. She pointedly asks,

"I just have one question. What did you do last summer?"
