When the brokerage firm of Blatch, Markham and Driggs dissolves, Markham steals company records and the option of a valuable mine. Meanwhile, Blatch, who wants the option to expire so he can then purchase it at a low price, hires attorney Burley Hadden to convince Driggs that he is trying to recover it. Hadden sees John Craig, a bungling construction contractor who needs $800 for his payroll, running nervously from the pop of a paper bag, and offers the supposed "dub" $1,000 to retrieve the papers, thinking he will fail. After Markham tries to dupe John, he meets Enid Drayton, Markham's ward, who is being held a virtual prisoner in Markham's mansion. With the help of a friendly burglar, they retrieve the option and other papers which prove that Markham and Blatch had been cheating Driggs for years. After Driggs rewards John and informs Enid that she owns a million dollar estate, she and John embrace.
