They've always only had each other. From the time they were children, quartered together in a facility; a last ditch effort to save Earth and humanity. Now grown, they travel the Galaxy, trying to find a safe haven where they can live in peace, finally able to escape the rampages of war. The four teammates face traumas they never expected as their faiths are shaken and the darkness of the past is brought into light by the appearance of a seven-year-old boy. Will the team make it out alone and in one peace? Or will the secrets that have been buried for a lifetime tear them apart?
