Yeah, basically he works for a black-ops team who can 'hack' the brain and cause others take actions beyond their control, like killing. They can't control thoughts, merely action like they take over musicle stimulation.
So he'd be on the run from others who can do what he does, so they'd be able to make someone take an action against their will - I would probably make it, that two or more mind controllers fighting to control one other person would cause harm or death, hence why he perhaps is more willing to run than kill innocent people.
Thanks for your advice, I will see if I can change the logline to improve its impact.
One last thing, the 'mind-control' will not be an 'super-power' so to speak, I actually want it to be tech based, that society is more melded with technology and the ethics and dangers that can pose when that technology is abused.
