Back in 1997, a little movie called I Know What You Did Last Summer came out. Loosely based on Lois Duncan's 1973 novel of the same name, the film follows 4 friends stalked by a hook-wielding murderer a year after they accidentally killed a man and covered it up.

The cast? It was the stuff of dreams: Jennifer Love Hewitt, Sarah Michelle Gellar, Ryan Phillippe and Freddie Prinze Jr. The movie was a box office hit and went on to span 2 (less successful) sequels.

Fast-forward to present day and we're ready to meet a new gang of teenagers running away from their crime and facing the consequences. The TV series I Know What You Did Last Summer has a similar concept as the original. However, it introduces new characters and creative twists that will keep viewers guessing about not only the identity of the stalker, but the fates of everyone involved. Fun!
