When a young Dutch woman killed a group of Nazis with the Dutch resistance, they caused an entire town to be sent to a concentration camp, they must save their countrymen anyway they can.

yeah it was a joke i actually like this quite a bit

That's just an unhelpful dick of a thing to say.

I'm not sure about all these loglines starting with "When". I don't think it's the shorcut everyone hopes as it reads too formulaic.

I think this is a workable concept. I'd posit it (something like) thus:

"A young Dutchwoman has to save her friends and neighbours when they are sent to a concentration camp in revenge for her Resistance group's success against the Nazis."
