Slick, well produced World War II series from the UNCLE production camp, ought to rate in this time slot. The opener centers on a trio of undercover men in occupied Holland shepherding a naive American electronics expert (Tom Bosley) around a windmill that becomes a German antiaircraft battery. The project contains a balanced portion of action and suspense, and the cast led by Don Francks and guest Bosley is quite ingratiating.
The good guys use a French boys choir to thwart the Germans. The choir cycles through town singing, each carrying a large loaf of bread in the basket on the bicycle. Cleverly hidden inside each loaf is a stick of dynamite (thus, the title). The dynamite is used to blow up the German subs sitting in the harbor.
