I have a very vague – call it abstract – memory of watching the beginning of this movie, but it seems not to exist, so I guess it was a dream.
The main character is a spy’s only daughter. Daddy (now dead) taught her to lose a tail, improvise a disguise, pick a lock, do basic forgery; normal father-daughter bonding stuff. She is now grown up with a career to which such skills are irrelevant, but in establishing scenes she practices them for fun.
She meets a girl (~14) who is running from Bad People and distrustful of the ostensibly Good institutions. She becomes the girl’s protector, and suddenly spycraft matters.
The local spooks become aware of her and are rattled. Who is this new player? Who is she working for? How long has she been here, and what else has she been up to?
Sounds good! Reminds me a little bit of Hanna, which I really like
