After living with the lie for 30 years that she heroically assassinated a notorious Nazi war criminal, a new clue gives a retired Mossad agent one last chance to finish the job she botched.

Part of the core premise is not just that she's coming out of retirement to hunt down the Nazi criminal, but that she's been living a lie for 30 years, pretending that the mission was already accomplished.? And it's her fault that the mission failed.? ?I deem that to be the hook.? What's at stake is not just terminating with extreme prejudice a very old Nazi war criminal, but of reclaiming her honor,? her honesty, of righting her wrong.

Intriguing!

I'm unsure if you actually need to include the "hook" (the lie) in this logline, as it seems like it might unnecessarily complicate the premise you're selling.

The core premise is this Mossad agent coming out of retirement to hunt down and kill the last Nazi war criminal who ever managed to evade/escape her. It might be important to the script that she pretended that she had killed the Nazi 30 years go. It doesn't really change the logline though.
