By the year 2123 climate change has decimated the Earth's most precious resource, her oceans. Worldwide droughts have created massive deserts where lush countryside once existed. The seas have turned toxic and the polar caps have disappeared. With its habitat quickly shrinking, humanity needs a silver bullet. Ten teams have been dispatched to Jupiter's sixth moon, Europa, and are tasked with retrieving a micro-organism known as Archaelleonous from the frozen moon's sub-ice liquid ocean. This precious resource is believed to be the key to restoring life to the Earth's oceans and resetting the climate.
