While conducting an investigation, the police went to a strange structure, a classified station. It is located underground and is not registered anywhere. The doors were opened, but there was no one inside. The owner cannot be found and what they are doing here is also unclear. There are some devices, apparently secret research was carried out. Perhaps this is due to something secret. Professor Michael, along with assistant Jessica, was recruited as a consultant. They need to inspect the premises and find out what they were doing here. It looks like observations were made from here, and then an analysis was carried out, but why is there no one now and what did those who worked here found out. It is necessary to collect documents, analyze them and reveal the secret in The Secret Station.
