Lois Duncan's book, "I Know What You Did Last Summer", spawned the movie of the same title, and its sequal, "I Still Know What You Did Last Summer". Julie and her three friends had ran over a young boy on his bike, and killed him. In a fit of panic, they decided to drive away, and make a pact never to tell another living person. It has been a year, and the group has fallen apart. But strange accidents are happening, first to Barry, then to Helen. And Julie can't explain the note, written in simple block letters and delivered personally to her house. I know what you did last summer.
