protip you wouldn't be trolling though.
It doesn't have a main plot at the moment. The main character is still considered in training and a newbie. But the first two episodes are related, and i guess one of the main plot points is the main girl is trying to find out what happened to her father.
right now though each episode is a stand alone episode and it's pretty much introducing the other characters, but in pretty god damned awesome alien ass kicking ways.
And if you know anything about ww2 aviation and the real pilots you'll actually spot dozens of references to their real life counterparts.
