After completing repairs and its reconnaissance mission, the Endeavour returns to Starbase 1 to lead the charge against the Romulan Star Empire in the Devron system. Starfleet orders Captain Campbell to ensure that whatever it takes, they must be victorious to ensure that Earth has a fighting chance in this war. Having to take out a station built within an asteroid and deal with a minefield, the crew of the Endeavour must take on more than one front to win this battle. They know that the Romulans will make them pay for every inch of the system they take, but it’s victory at all costs!
