When a disgraced former marine is confronted by his wounded daughter, he must protect her from his former clandestine employers who want to use him to kick start an old MKUltra programme

I feel that the elements in this are all exciting, but there are lots of gaps, which can I found a bit overwhelming. Perhaps consider breaking it down a little and spreading those concepts out?

e.g.: A (adjective) (profession) is contacted by his estranged and badly wounded daughter, who claims to have been brainwashed by the CIA; he must now attempt to keep safe from her former employers while rekindling their relationship.
