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.

After the fall of Mussolini, the Jericho team's mission is to locate an Italian official who can tell them of the Axis plans. To divert the Germans from their real mission, they make it look like they are out to capture Mussolini himself. But the cunning German in command does not take the bait, and to make things worse the Italian partisan contact Jericho freed to help them does not trust them any more than he does the Germans.

To obtain the information on the German plans, the team has to agree to Ferretti's demand that they take him and his children out of the country with them, even though this will slow them down. They are thus forced to take refuge in a house, and hide from Major Von Zeeny and his men when they take the house as their command center.

In order to destroy a German decoding installation in Paris, the Jericho team must tunnel into it from a dress manufacturer's shop across the street, which does not please the owner of the shop.
