Kept

Twelve massive ships leave the dying earth, heading into the great unknown, seeking new life among the stars. One of the ships, Gaia, crashes on Kepler, which is already inhabited. Now at the mercy of the alien race, the humans are held in an underground cavern. Would they still have gone knowing that they would be stripped of all humanity? Under the constant eye of the aliens, a few men discover there may be a way out of the cavern. But to where? How will they escape and what will they encounter if they succeed?
