They team up to hack into the school and change their failing grades. Jack is hesitant at first, but gives in. Thinking that they've succeeded, they celebrate. Soon after, each one of them becomes blackmailed by an unknown person disguised as "Brittany Taman." Everyone is confused due to the fact that Brittany Taman was a student who committed suicide. Ricky reveals that Jack had something to do with her. The unknown person gives each of them different errands. They, then proceed to find out who their blackmailer is. Meanwhile, in present time, Jack is seen at the hospital severely burned. He repeatedly says "Brittany," leaving his parents confused. Reverting into the backstory, they soon discover that the blackmailer is their own science teacher, Faustin. He had witnessed Cameron hacking into the school computer. He threatens them to get him a specific amount of money at any cost or else he would tell the police. The group becomes stressed, not knowing how to get the money. Ricky considers telling the authorities, but his family is forced to move back to Russia. Feeling pressured, Carla considers overdosing on pills. Alex discovers a way to steal 5 million dollars. They all team up, once again, to steal money using fake IDs and add all the money to the school account online. Once they obtain all the money needed, they meet their teacher and give it to him in exchange for their freedom. Cameron, still enraged by everything their teacher put them through, confronts him, forcing Faustin to pull out a gun to kill Carla and Cameron. Jack is also shot, but is still alive. Laura threatens Alex to never speak of the incident again and to move far away. Meanwhile, she and the principal go on the school account to discover that all the money the kids had stolen is gone. Alex then receives a message on her phone that all the money has been deposited into her own account. A video message sent to the principal reveals that Brittany faked her death, and that Jack lied to and used her while he was still with Carla. Carla, later, made the whole school turn against Brittany, which caused Brittany to want to commit suicide. Also, Cameron and Ricky wanted to take advantage of her. The video ends with her saying that these haters will pay for everything they did to her. It becomes clear that there is much more to this story than meets the eye.
