When Steve's friends Max, Lucy, and Henry get their hands on a map with the location of the legendary Mine Mountain, Steve questions if the map is a fake. Going to this fabled mountain, rumored to contain an endless supply of diamonds, is every treasure hunter's dream. Many believe the mountain doesn't exist, and although Steve is doubtful about the map's authenticity, the gang convinces Steve and Kyra to embark on a journey to find this magical mountain. On their trip, Steve and his friends stumble upon a town filled with friendly folk. While there, they meet other treasure hunters who are also searching for Mine Mountain. As the group joins forces with their new treasure hunter friends, creepers attack them. The closer they get to the famed mine, the more creepers appear. The group doesn't know if this is the work of a griefer or if the creepers are trying to hide something.
