Masks are something we all wear, some of us literally and some of us in a more figurative manner. Hunt is back and the IMF are in deeper than ever before. There's a new agent working to help him in the field and some other matters that complicate the situation. Hunt must be rescued before he can be of help to anyone else. Once they help him, his team helps him to pinpoint the source of the trouble. Once they have the person/problem pinpointed... it's just a matter of time. The deeper they get, the more trouble they get themselves into. Then the unthinkable happens. They must enact "Ghost Protocol". You might ask yourself what that is, but honestly, it is best summed up by watching the story unfold. Once Ghost Protocol is enacted, they realize how limited they are in pulling this off. Ultimately taking each member of the team to new heights. This fourth installment is definitely the best of the series (so far), the way it leaves off leads into something much more that could still be in the works. Finally, a complete story and dialogue that though it still has errors, the story and characters are strong enough to carry it through. If you're a fan of the Mission: Impossible series, you'll love this one. Even if you aren't, there's enough action and drama to this to carry it even without the others.
