A loving family man must go on the run after a powerful government program uses him as a proxy to commit murder. Now, in order to expose the truth, he’ll have to reveal his own dark and secretive past.

That's great a really like this version.

A family man struggles on the lam to prove his innocence after a corrupt futuristic government implants the consciousness of a hired assassin into his body to commit a murder.

Thanks for your help, I will look to rework it. I guess I want to get across in my logline that he is framed as when he committed the murder he wasn't in control of his body at the time. So, the assassin would load himself into a person, who may have the target's trust etc, and simply walk in and do the deed, once done the assassin transfers the person back in.

So, the film will be able proving your innocence when everybody saw him do it.
