The corrupt Boss Hogg (Sorrell Booke) learns that a wealthy industrialist is offering a $200,000 reward for anyone who can lead him to his long-lost niece Vivian Stewart, who happens to look exactly like Daisy. Boss hires a hypnotist to convince Daisy that she is the long-lost heiress so that he can claim the reward. Unfortunately for Boss and Daisy, the industrialist also has two other heirs who are not happy to see "Vivian" return to take their place in the line of inheritance, and they set out to murder her.
