Synopsis:
Batman and Robin fail to thwart two robberies each made by an identical fat man. At first they think it is a single crook, but Batman soon deduces that the men are twins. Batman tracks down the twins to their hide-out, but the twins, Tweedledum and Tweedledee, are expecting him and have set a trap. Batman escapes the trap and springs his own trap on the crooks, ending in their arrest.
