A pair of mobsters storm the office of a university professor, only to find the professor missing. The trail eventually leads to the waterfront Gas 'n' Charter, which has been run by Bwana and Kito ever since they were mysteriously abandoned by their adoptive father. When given the opportunity to help a young woman named Lina, the pair jump at the chance, as they are seriously behind on their electricity bills. Lina is seeking a lost book that may hold the illegal secret to reaching the Underland. Unfortunately, their airplane hasn't been flown in years, and will need a variety of parts and repairs in order to take off.
''Chapter Two: Into the Mist''
The group heads to the gloomy, mist shrouded town of Port Artue. Upon arrival, the trio find themselves confronted by local police. Bwana and Kito are thrown in jail, and Lina is taken away by the police chief. Bwana and Kito then attempt to find a way to escape from prison, find Lina, and attempt to discover how their adoptive father was connected to the mystery of the Underland.
''Chapter Three''
In the final chapter, the trio heads into the depths of the Underland where they discover a huge mining facility belonging to the Armando Power Company. Bwana and Kito return to the city of St Armando in hopes of finding Professor Moorhead who they believe can help them stop the power company, while Lina ventures further into the Underland.
