The starship Challenger is on a 115-year-long mission exploring other galaxies for suitable Earth-like planets to colonise.

The current four crew members were born on-board and have never left the ship. From birth they've been looked after by two 'Angels' - voices surrounding and guiding their every move. Any advice is followed without question. A dangerous situation, perhaps, if the Angels aren't that angelic after all...
