Here is the problem, in both your logline attempts you begin the logline with the part about how 20 years ago a secret service agent kills the President to save the Presidency.

That is all set up.

Then you go on to tell us that, now 20 years later, his daughter is president and he must rescue her. Which is highly improbable.

It seems to me that the ‘hook’ to the story is the idea that there is a potential “Hitler in the making” who was president and a Secret Service agent ends up killing him in order to save the Presidency and our nation’s freedoms.

Since that seems to be the hook, that is the story you should tell.

Tell the story of a secret service agents moral dilemma. Tell the story of a President spiraling into madness.

That is a far more compelling story.

In your logline the bad guy is a city, Is there a person in your story who could replace the city as the bad guy?

You say the 157-year-old woman is a runaway but you don’t tell us why she is running. As a result, we don’t know what the stakes are.
What causes the woman to run away in the first place, what event sets the story in motion?
What bad thing will happen if he the lead character doesn’t save her? What is the lead saving the 157-year-old woman from?
