A group of friends are participating in a secret game master escape room challenge. They are divided into two groups, with the girls (Jazz, Chad, Rebecca, and Matt's partner) trying to spy on "Project or Go" while the boys (Chad, Matt, and Steven) follow the game master. The groups are trying to uncover clues and piece together what's happening. They discover that Project or Go and the game master seem to be working together, and they find several cryptic clues, including water bottles with notes and symbols. As they try to decipher the clues, they begin to suspect that one of their own group members might be "Project Arthur" and that the game master's intentions might not be what they seem.
