So my take is that, since a lot of the album is about the WW2 era (said by the band), this song is about a guy who loves a girl that is in danger of being caught by the Nazi's for not being part of their "perfect race". So, he didn't give her up, even though he spent time in prison because of the fact that he was "protecting" her. And when he gets out of prison, they are going to escape to America, to get away from the Nazi regime.

Just my two cents.
