The Terran Empire rises again. After the capture and execution of Regent Worf, the Terran rebellion grew in strength until they eventually overpowered their oppressors. Only one year later a new liberated Terra is expanding their influence and power, pushing back a crumbling Klingon/Cardassian alliance.

A brand new warship, the ISS Wayfarer is launched by the new Imperial Starfleet. Under command of former slave, Captain Akeno Misaki, her mission is to reconquer former Terran space, liberate their people and take back what was once theirs.

However, the ISS Wayfarer encounters a crack in space, and finds itself in the prime universe. Terran Captain Misaki begins a series of raids on Starfleet and Klingon bases and ships, their mission to acquire new technology to strengthen the Empire and take what they need to survive.

The Klingons blame the USS Wayfarer for these attacks on their space, seeing it as the Federation attempting to push their borders after they've been weakened by war. After proving their innocence, Starfleet gives the crew of the USS Wayfarer a chance to stop the Terran Ship and to clear their name before the Klingons declare war.
