Penned by the same author of "Scream", "I Know What You Did Last Summer" reeks of plot twists, good old fashioned slasher-ific deaths, and a memorable cast.
Julie James (Jennifer Love Hewitt), her boyfriend Ray (Freddie Prinze Jr), her best friend Helen (Sarah Michelle Gellar) and boyfriend Barry (Ryan Phillipe), find themselves all being caught up in the accidental hit and run of a man on the fourth of July
Reluctantly, Julie agrees to go along with her friends plan of ditching the body off the end of the pier and hoping it'll be dragged out to sea never to be seen again.
A year passes, and Julie is attending college; having lived with the guilt of murder for a year, she's no longer the smily bright-eyed bubbly girl she used to be, surprising her mother to a dark, palid and withdrawn version of herself when she goes home for Summer Vacation.
As Julie tries to settle in at home, she suddenly finds herself being thrown in to the terror of last fourth of July all over again when a mysterious envelope comes through the mail, the contents claim "I know what you did last summer".
Now, she must draw Ray, Helen and Barry together again so they all can unravel the mystery and find out who's behind this devious note. But as strange things begin to occur, Julie realises what she thought was a warning, may be a definite death threat when a dark figure in a slicker and a fisherman's hat begins to stalk the group.
