When five friends inadvertently cause a deadly car accident, they cover up their involvement and make a pact to keep it a secret rather than face the consequences. A year later, their past comes back to haunt them and they’re forced to confront a horrifying truth: someone knows what they did last summer…and is hell-bent on revenge. As one by one the friends are stalked by a killer, they discover this has happened before, and they turn to two survivors of the legendary Southport Massacre of 1997 for help.
Director Jennifer Kaytin Robinson teams up with screenwriters Leah McKendrick and Sam Lansky for the fourth installment in the “I Know What You Did Last Summer” franchise and a sequel to the 1998 film. Another hook-wielding killer appears 27 years after the Tower Bay murders.
Reprising their roles from previous installments are Freddie Prinze Jr. and Jennifer Love Hewitt, along with new cast members Madelyn Cline, Chase Sui Wonders, Jonah Hauer-King, Tyriq Withers, Sarah Pidgeon, Billy Campbell, Gabbriette Bechtel, and Austin Nichols.
I KNOW WHAT YOU DID LAST SUMMER will be in theaters July 18th, 2025.
