Five teens are invited to a locked-room, murder mystery night and the one who solves the mystery will will a $50,000 scholarship. But when they arrive and find out who their competition is for this scholarship, they realize that they have an actual death (murder?) in common. They quickly realize that the scholarship was a ruse and they're really there to figure out/confess to what happened a year about when another boy died.
This is a fast paced thriller, very much in the vein of I Know What You Did Last Summer, very much Clue meets Pretty Little Liars.
