As described in a film magazine,  George Washington Magee (Cohan) bets a companion $5,000 that he can write a bestseller in twenty-four hours. He goes to an isolated summer hotel in the mountains, receives the only key to the place, and sets about his task. Soon he is interrupted by complications as guests arrive, unexpected and uninvited, each with their own key to the deserted hotel. Two hundred thousand dollars gets deposited in the hotel safe, a young woman is shot, and, while the author holds the crooks at bay waiting for the police to arrive, they cook up a scheme to turn the tables on George. The woman's body disappears from the room, and the crooks are marched off to prison by U.S. Secret Service men. The caretaker returns the following night and congratulates the author on his success, and a lady reporter capitulates under the smiles of the industrious writer.
In Fantastic Movie Musings and Ramblings, Dave Sindelar wrote, "Cohan himself appears in the lead role. This was his first of only a handful of screen appearances, and he does a fine job...The plot is far-fetched and sometimes confusing, and the fact that some sections of the plot are replaced by title cards doesn’t help, but I like the backstory, and there’s definitely an air of parody to the proceedings. At this point of time, I’d have to say it’s my favorite version of the story."
