Dick Barton (Don Stannard) has come to the countryside where he battles an evil Nazi plot led by Schuler (Arthur Bush) to poison London's water supply with a deadly bacteria.
Barton has discovered the plot by accident when some lobsters are delivered to him by accident by a distracted boy who is more interested in his Dick Barton comic! Schuler and his inept goons try to kill Barton a number of times but fail miserably. Finally, Barton is locked in a suit of armour while the Nazis prepare to test their bacteria on him...
Based on a popular BBC radio drama, this is an enjoyable romp. Fast moving nonsense that shouldn't be taken seriously, though it is maybe a little too comedic at times. Snowey (George Ford) and Jock (Jack Shaw) are there to help/hinder Barton in equal measure.
