The Gay Adventure is a typically verbose and complicated comedy-drama from the pen of playwright Walter Hackett. A gang of American con artists manage to convince gormless Englishman Darnton (Barry Jones) that he's a direct descendent of French swashbuckler D'Artagnan. Their motive is to shake down a French family for inheritance money, but Darnton has no way of knowing this. Enchanted by the notion that one of his ancestors may have rubbed shoulders with the Three Musketeers, Darnton imagines that he's back in the 15th century, crossing swords with the minions of Cardinal Richelieu. In traditional movie fashion, all of the characters who appear in the "modern" portions of the film likewise show up in period garb in the flashback sequences.
