It’s the aftermath of “Apocalypse Now.” Captain Willard is back stateside and the higher ups are giving him the hero treatment: your country thanks you for what you’ve done, earnest and firm handshakes. Yet he is troubled, even angry. And the brass is on to it. He’s giving vibes he might break down, kill some people—or even worse, tell his story. He never had anything to lose, you know? Heck, that’s why he was chosen in the first place. There’s whispers of what to do. Get rid of him? Take him out before he becomes a problem? Or flatter and coddle him into complacency? This sequel is called “Contingency Plan.”
