Summary:Johnny Frenchman uses humor to drive home the point that, despite all previous rivalries and hostilties, the French and English should pull together during WW2. Aldwych farceur Tom Walls plays Nat Pomeroy, harbourmaster of a Cornwall fishing village, who is continually outsmarted by clever French fish poacher Lannec Florrie (Francoise Rosay). Pomeroy is further aggravated by the fact that Florrie's son Yan (played by French-Canadian radio favorite Paul Dupuis) is busily romancing Pomeroy's daughter Sue (Patricia Roc). But when the Nazis rear their ugly heads, the Cornish fisherman and the French miscreants band together to thwart the German menace. Many of the cast members of Johnny Frenchman are actual Cornish villagers and members of the Free French resistance movement.
