Jim Nugent and his sweetheart, Bess Forrest, go auto riding. They break the speed limit law, but manage to get away. The auto number is 666 and Jim reverses it so that it reads 999. Later they are arrested and it is discovered that 999 belongs to a car used by a couple of bank robbers who have just made a good haul. Jim and Bess are pretty badly scared until the robbers are caught and brought in. Of course Jim declares that the number was hung upside down in the garage, and promises to make his machine behave in the future.
