Julie James, a high school senior, is thrilled to receive her acceptance letter to Smith College. However, her excitement is overshadowed by a mysterious note that reads, "I KNOW WHAT YOU DID LAST SUMMER." This cryptic message sends a chill down her spine, reminding her of a dark secret she shares with her friends. The note is a stark reminder of a hit-and-run accident they were involved in the previous summer, which resulted in the death of a young boy.
