Long time ago there was one best friend group they know each other since grade 2 and now they are in grade 12. They knew each other not because they parents are friends but they all have the same dream, they want to be people who work about mysteries thing. When they finished grade 12 they plan to start working about  mysteries,they post on social media if any company want them,They wait and wait finally one company call them. They have to find out what is under the mysteries ground. They walk and dig down suddenly  they hear some thing was making noise ... the noise was SO Loud...
