When a vindictive cyber-terrorist steals nuclear activation codes, a distrusting special agent must use an experimental machine to enter his mind and retrieve them before he instigates a global conflict.

Thanks again for your help. That is why I have added the 'Untrusting' element, as someone who spends his time learning the secrets and hidden lives of others is going to struggle with his own personal relationships and never have that deep connection with someone as he'll always be searching for what is under the surface. Something that perhaps with our partners we all wish we could look inside and see what is ticking, but from time to time you have to learn to trust, which is something my character will learn, and in doing so will develop a connection.

Exactly.

The idea is that an audience member will empathise with the MC for one reason or another. As this empathy is established the audience member will see a bit of him or her self in the MC and follow them on the journey in a way that replicates themselves going on the same journey. This makes the viewing experience a personal one for the audience and masks the strategised plot structured around the inner journey.

The unity of action of the MC drives the audience to follow them as they fight against or react to the obstacles in the story of the world.

The unity of action and empathy are the substance of interest for the audience.

It does, it helps a great deal. So, really need to nail a description for my MC, and tie that to the story. So on the surface it is about a team trying to obtain codes to stop a potential war, but underneath - we have the characters inner journey, which could be one of redemption to greed to discovering faith, but whatever I choose I must tie it to the story.
