Jack Stradon leads a resistance that is loosing a war against an oppressive nation. The nation seems to know his every move, and every failed plan means one more man down. Just when it seems it's his time to die, he gets an offer he can't refuse. Leaving his former life, and leaving all his men behind, he starts a new life working as a tactical planner, helping the men he swore to kill. Soon he grows in rank, and then joins the force that hunted down him not so long ago. He finally tracks down the sole survivor of his squad and is faced will a choice-kill him, or die.
Just something I came up with.
