Here's everything that we know.

What is the plot of I Know What You Did Last Summer all about?

The sequel film will once again feature the bone-chilling character of the Fisherman, as revealed by the trailer, setting forth on his rampage. There's once again a teenage group that causes an accidental death by way of a car crash, and a year after this incident, the past comes back to haunt them. The official synopsis reads:

"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 opens up about the sequel film

Jennifer Kaytin Robinson is the writer-director who has helmed the sequel of I Know What You Did Last Summer.

Speaking in an exclusive interview with Entertainment Weekly, Robinson opened up about the journey to make the film and the creative process that went on behind the scenes. Speaking about her biggest influence for the film, Robinson noted:

"Visually, for me, it was about going back to my biggest touchstone for this movie, Jaws, I was like, 'I want beautiful colors, beautiful setting, blue water, red blood.' For me, it's kind of like a throwback, and what I hope is that it feels like it's fresh in its nostalgia."

She further added about her desire to make the sequel stand out on its own merit:
