Shrouded in endless darkness and the threat of death, can the space explorers detect the chill of unknown creatures lurking in every heartbeat? In this life-and-death chase, what kind of trust challenges and moral struggles will they face? When companions are cruelly devoured one after another, can they find a glimmer of hope in this space killing with no one to turn to for help?
