After exhausting planet Earth, humanity has moved out to live "on the stars."
With your closest neighbor lightyears away, the "on the stars" lifestyle guarantees a level of privacy unmatched in human history. But even ultimate privacy doesn't need to come at a cost when modern technology can instantly whisk you back to civilization.
But when that modern technology unexpectedly fails, three private vessels find themselves completely unprepared for the isolation that follows. The three crews have very different strategies to cope with a radical change to the status quo.
Will they have the supplies and wherewithal to survive the weeks and months that it will take to get back to civilization?
