People within Starfleet Command are selling secrets and weapons to a third party and it is up to Gabriel and Mystique to find them and who they are selling to, only to encounter two enemies they both do not expect.

The USS Yorktown is called to Tantalus III to settle a civil rights violation on that world and prevent a civil war that will affect the nearby populated systems.

As Raven hunts down the people that are still loyal to Trask she will encounter another mutant that is just like her while at the same time she will encounter someone that is more dangerous than Trask

One of the Yorktown's crew is not who she says she is and when Gabriel Valkyrie is taken prisoner on an unexplored planet, she is the only one who can save him.
