Setting:
By 2050, humanity has finally colonized Mars thanks to the efforts of one man, Jeff Murray. To avoid Mars’ high radiation levels and inhospitable temperature changes, he built a city underground. This city was named Mars MPO. Free of the constraints that often plagued businesses and researchers on Earth, scientists and entrepreneurs flocked to MPO.
Recently, Dr. Albert West has migrated to MPO at the personal invitation of Mr. Murray. West has been working on a cure for Alzheimer's disease in a race to save his wife, Jennifer, from dementia. His efforts are cut short; a lab accident leads to an accusation of murder and a prompt prison sentence.
We join Dr. West a little over a year into his prison sentence. It’s been a week since the guards mysteriously vanished. Dr. West is about to find out why.
