Overview

A strange cloud drifts over the base and causes most of the crew to be stricken with illness. A monster, the 'cloud creature' appears out of the cloud and runs amok on the base. A voice from the cloud explains its purpose. The base must give up its life support in order to prevent the cloud from dying. With most of the crew indisposed through illness, it is down to Maya to employ her shape-shifting skills to beat the creature.
