To stop her ex-husband from stealing the Mona Lisa, a world-class cat burglar turned security expert must illegally install her own security in the Louvre.

Hi! Good news is that your logline definitely made me think that most of the movie was about her attempting to install the security equipment. So, it's clear. However, I have to agree with patrockable... not really a movie, IMHO.

The entire second act is her figuring out better security and then illegally installing it without the Louvre?s permission or knowledge? That sounds boring.

I don't want to see an hour of a woman trying to install security in the Lourve... I want to see a cat and mouse game with the ex husband. That's your hook... and the installing security thing actually diminishes it. Anyone else think this is the hook?

Hey guys, I appreciate the feedback -- THANKS!

Maybe I need to reword it, but I definitely don't want to lose the last part -- b/c that's the movie's Hook and the hero's main Goal. The Louvre doesn't believe her b/c of her criminal past and they think their security is good enough (it truly is some of the best in the world).

The entire second act is her figuring out better security and then illegally installing it without the Louvre's permission or knowledge.

IMO, A world class cat burglar turned security expert must stop her ex-husband from stealing the Mona Lisa.? is too generic, there's not enough info. How is she gonna stop him (stun gun, break his arm), where is she gonna stop him (America, Germany)?

I think maybe changing just one word, Illegally to Secretly, helps the flow.

Thanks again for the feedback!
