“Callan” (Edward Woodward) was retired from his top secret job after his boss “Hunter” (Eric Porter) thought he’d lost his edge, but now that very man is courting him to return for one very special task. That will involve him killing a man called “Schneider”. If he does this, then he will be reinstated no questions asked. Thing is, though, “Callan” isn’t just an hit man, he wants to know a little bit more about his quarry and so sets about getting to know this man (Carl Möhner) who loves replaying Napoleonic battles using hand painted, cast-iron, armies and who shares a seemingly innocuous life with his wife (Catherine Schell). His employer isn’t convinced with these methods, so decides to let his replacement “Meres” (Richard Egan) make up a plan B - in which it is quite possible that “Callan” could end up being collateral damage. What now ensues is a decently paced, if slightly confusing, thriller replete with just about everything save a poisoned umbrella tip. Woodward and his fixer “Lonely” (Russell Hunter) have reprised their roles from the successful ATV television series from the late 1960s and in many ways this is just one feature-length episode from that. It works fine, with solid production values and it’s even got a little bit of soul.
