The show has empowering messages about the strength of teamwork and the sense of accomplishment to be found in seeing a challenge through to its end. The teens must use a variety of problem-solving tactics to unravel the mysterious clues they're given.
No violence, but the story hinges on mysterious happenings and the unsolved disappearance of a teen. Tension runs high when spooky things happen (writing appears on walls, objects are knocked over by an unseen force, etc.).
Teen crushes include some kissing and hand-holding, but overall the show puts these relationships in a positive light. There's no giddiness or suggestive content, but rather a mature approach to dating from teens who care about and respect each other.
The show is linked to a website that allows viewers to try to solve the story's mysteries and offers additional clues that accompany those they see in each episode.
