When a 70 year old KGB sleeper agent loses the will to kill, he decides to become his target’s guardian against assassination instead.

Agree with the others. Would love to see this. I think the logline is fantastic accept I'd like to know who the target is. Is it someone important?

This is gold! I want to see this!

Hey, I like it! Who better to protect against a hit? Reminds me of Red.
