When Harry bought a car he could not have foreseen the problems it would cause him. Unable to get reasonable mileage from it he investigates and discovers a false petrol tank has been fitted and hidden inside are dozens of bars of gold... Where more weak-willed men would keep the treasure for themselves, Harry does the decent and honourable thing and hands it in to the authorities. Unfortunately the weak-willed man who hid the gold there years before finally comes looking for it. A campaign of harassment and attempted violence forces Harry on the run from the man's gang and, it would appear, the authorities themselves who are suspicious about the whole story. Halfway across Europe in post-war Germany Harry thinks he's safe staying with a local couple and their beautiful daughter, but the bad luck that has dogged him since his unfortunate purchase is about to find him once more.
