to Nazis.
I'm reminded of the Sound of Music, particularly the transition of Rolf, the boyfriend of Liesl Von Trapp, who turned on the Von Trapp family after becoming a Nazi.
Rolf, one of the Nazi guards, slyly remains behind as the others search the roof area, and he discovers them as they emerge from their hiding places. As the family escapes to the convent's car, the Captain remains behind and challenges the pistol-wielding young lad:
You're only a boy. You don't really belong to them...Come away with us before it's too late...You'll never be one of them.
Although the Captain safely removes the revolver from the boy's hands, Rolf summons the other officers. The entire family speeds off towards the mountains. Zeller and his men hear a car racing away and rush out to their vehicles, but they can't get them to start. By an upstairs window, the sisters confess to the Reverend Mother that they "have sinned" - they exhibit vital car parts from under their robes.
