Brian Godfrey and Arnold Lambert are clerks in the diamond broker's office, both interested in Mildred St. Pierre, the daughter of an old employee. For a while she is impartial but Arnold is too impetuous in his addresses and she repulses him. Gilbert Howell, a traveling salesman of the firm, puts into the vault a sealed package containing valuable private papers. On the same day is placed in the vault, a number of fine uncut stones in a similar package. When Howard starts on his usual tour, he takes from the vault what he thinks are his papers. That same evening, old St. Pierre, recalling the fact of leaving some very important papers on his desk is worried and decides to make sure by going back to the office alone to place them in the vault.
