I Know What You Did Last Summer (Season 1)

I Know What You Did Last Summer (2021) is Amazon's eight-episode reimagining of the slasher franchise — watch it online on iFILM. The story moves from California to sun-drenched Hawaii, where a group of newly graduated friends share a deadly secret after a road accident on the night of prom.

A year later, the messages start. Someone knows. Madison Iseman carries the show in a dual role as twin sisters whose lives went in opposite directions after that night, while Bill Heck plays their father — a man with his own things to hide. Creator Lόgan Kibens treats the first half of the season more like a psychological drama than a straight horror, letting dread build before the bodies start dropping.

For anyone who burned through the original film cycle, this version offers something the movies never had: time. More episodes means more suspects, more texture, more of that uneasy Hawaiian light that makes everything look beautiful and wrong at the same time.
