In a modern European country, a deadly terrorist group carries out an attack, a naive young school dropout must get would-be victims to safety.

What about this?

When his mentor set's him up with a bomb in a train terror attack, a naive young man, while being accused of terrorism must evacuate passengers which will be killed in his name

I have done a rewrite on my logline. Tell me what your guys think.

"When his mentor, a terrorist in disguise set's him up in a train terror attack, a Norwegian dropout, must evacuate the potential victims which will be killed in his name, before a bomb goes off."

The interesting part about the logline is that he is being set up, however the vague nature of the inciting incident raises too many questions with regards to the "how and why" of the situation.

As the logline lacks detail with regards to the specific events, and actions taken with in them, it seems like another setup story only with slightly more topical subject matter. It's the particulars of your story and the inner journey of the MC that will help you write a compelling script and make it a must read.

In other words, his mentor sets him up, but how does this happen and why?

Must stop the plot - what plot? Will it happen around a big summit or major event? And what kind of attack?

These are all the details that will make your story unique and therefore interesting.
