Flirtatious Jerry "makes a mash on" pretty Gladys while both are viewing a billboard displaying handsome posters of Julius Caesar, advertised for production in a ten-twent'-thirt' house. Particularly impressed is Jerry with the resemblance of the picture of a beautiful Roman maiden to Gladys. Agreeing to meet again, they separate, Gladys for home, Jerry for a nap, which he proceeds to enjoy in a straw-filled packing case he finds in a nearby alley and (as it must happen for always-getting-into-trouble Jerry) alongside the cache of a lot of loot hidden there by a couple of burglars. Jerry dreams he is a Roman emperor and that he and Gladys are having a great time, winding up with his slaves putting him to bed in the royal chamber. It is this handling of him, the patting of the royal bedclothes about him, that wakes him, and be discovers that someone is really handling him, for a couple of policemen are putting handcuffs on him, believing him to be the burglar they are looking for. This is not the end, however. He proves an alibi, his release, and joins in the search of the cracksmen. Then follows some thrilling as well as comical scenes. Jerry discovers the robbers' den, valiantly attacks them; they knock him unconscious, set fire to the place, and escape. Jerry revives when a flood of water is poured on him from the firemen's hose, and the instant he escapes from the building there is a terrible explosion caused by combustibles in it. Jerry keeps going after the crooks, gets them; the loot is recovered; it had been stolen from Gladys' home, and Jerry makes himself solid.
