On Tuesday, Alexis Frost is in American History class, exhausted from having another difficult night with her mother. The classroom phone rings for Alexis. Alexis’s first thought is something may have happened to her mother, but the phone call is about her volunteer work with the search and rescue team.

Nick Walker is texting Sasha Madigan trying to get her to study with him tonight. He hopes there will be a lot of copying notes and kissing. His phone vibrates with a message: The Portland Search and Rescue (SAR) team has been called in for a search in Forest Park. Nick hurries out the door hoping someone from class will tell Sasha.

Ruby McClure feels her phone vibrate in chemistry class. Ruby prefers logic and directness and appreciates the use of military time in the SAR message. She estimates how long it will take her to change into hiking clothes and pick up her SAR backpack before meeting the team at the sheriff's office.

12 volunteer teens meet in the Portland County Sheriff’s Office to be divided into teams. The plan is for each team to start on opposite sides of the park to look for Bobby Balog, a 34-year-old man with autism spectrum disorder.
