What would you do if all you had ever known came crashing down?
    
    That's the question that plagues Ryder, as she uncovers several insidious plots and must decide who she can trust and fast. 
    
    Should she trust her second in command, Blade?
    
    Or the new recruit, Nick Marshall?
    
    Can Ryder decide in whom to place her trust, before it's too late?
    
    Will Ryder be brought down or will she fool them all? 
    
    And, as the past begins to haunt the future, who will make it out alive?
