Addy, Bronwyn, Nate, Copper, and Simon are all in detention for the same thing. Someone planted phones in all 5 of their backpacks, knowing they would suffer the consequences. But who did this, and why? "I'm thirsty." Simon complains. So he gets up a gets a drink from the sink.
Then, all of a sudden, the 5 students all hear a big bang! They rush to the window and see a car accident take place right outside their classroom.
When they look back they see Simon clutching his throat and screaming. Everyone panicks and tries to help Simon. They remember SImon has a peanut allergy and raid the nurses office to find Epi pens, but they seem to be missing. They call 911 and they rush him to the hospital.
