A sister and brother, Esther (a guitar player) and Jarvis (a drummer), have been accused of changing their grades in the computer system. They both swear that they haven’t done this, but their digital footprint indicates their logins were used to make the changes at 4:02 on Thursday, March 1st. They claim they couldn’t have done this because they were practicing in their rock band for the school Lip Sync. In order to prove themselves innocent, they have to find out who stole their account information to make these changes.
