I Know What You Did Last Summer

I Know What You Did Last Summer (2025) is a slasher you can watch online on iFILM, directed by Jennifer Kaytin Robinson. Five friends cause a fatal crash on a dark Southport road, then hide the body and swear to never speak of it. One year later, the silence comes with a price.

On the anniversary, each of them receives a note carrying that line. Then a killer with a hook starts picking them off, one at a time. Chase Sui Wonders and Madelyn Cline play two friends whose bond cracks under the weight of the secret. Unsure who's behind it, the group tracks down the survivors of the 1997 Southport massacre, turning to Julie James and Ray Bronson, with Jennifer Love Hewitt and Freddie Prinze Jr. back in the roles.

Robinson, who made the dark comedy Do Revenge, reboots the late-'90s favorite with a new cast and a meaner streak of irony. Bringing back the original leads isn't a throwaway cameo here; it stitches the two timelines together. If you like teen horror where a rumor cuts as deep as the hook, press play.
