A CSIS agent returns to duty to stop an eco-terrorist leader who’s missing his original face, and his followers who are in possession of the American government’s plans for the next 81 years.

There the problem of suspension of disbelief that goes along with any story.

In the case of your story, the reader has to suspend their disbelief that the US government is competent enough to carry out an 81-year plan.

LOGLINE UPDATE #1:

The best agent working for CSIS is given a secret mission to stop an eco-terrorist leader and his co-conspirators from making the government's devious plans for the next eighty-one years public knowledge.

While this isn't bad writing, it is not a successful logline in my opinion. You present our protagonist, and then you present some other aspects of our narrative world, but it lacks a clear plot. A CSIS agent returns to duty (okay, that's good set-up) to stop an eco-terrorist (alright, there's his antagonist) who's missing his original face (what? clearly this needs set-up in your world, since in our known universe people don't lose their faces, but to avoid over complicating your logline by explaining the scifi nature of this world, maybe just not mention that. Execs will learn it when they read your script, but for now just him being an eco-terrorist is enough), and his followers who are yada yada (this part makes very little sense as well. 81 years? That's a random length of time. And why does it matter that they have the government's plans? If you're adding info, you need to also include why it adds to the antagonism of the plot).

So, An ex-CSIS agent returns to duty to stop an eco-terrorist, that's all good. I would cut the rest and figure out a way to integrate more succinct but important details to the plot.
