The Enterprise enters the mirror universe to recover the Defiant. it is not welcomed. after finding their missing ship, the Enterprise engages the enemy ships (I.S.S. Columbia, I.S.S. Currie, I.S.S. Coto) and deals heavy damage before retrieving their target and returning to the Federation.
this is why i prefer to make digital models, instead of real lego. Also, this was my first space combat model. Well, the original was.
