Miss Tatlock's Millions

Movie stuntman Tim Burke is offered $1000 for a couple of days of work by Denno Noonan. Noonan was the "social secretary" for the mentally incompetent orphan Schuyler Tatlock. Schuyler's wealthy relations shipped him off to Hawaii to get him out of the way and paid Noonan very well to watch over him. However, Noonan got drunk two years ago, and when he returned home, he discovered that Schuyler had found some matches, started a fire and was burned to a crisp. Noonan has not bothered to notify his family, liking his big monthly paycheck. However, he has received a telegram telling him to bring Schuyler home for the reading of his grandparents' will. Noonan hires lookalike Tim to impersonate Schuyler.

Tim dyes his hair and affects the voice and mannerisms of Schuyler the best he can. Everyone is fooled, including Schuyler's younger sister Nan, the only member of the family happy to see him. Practically the entire fortune, about $6 million, goes to Schuyler. Miles, Gifford and Cassie, his greedy uncles and aunt, scheme to be named his trustees. Miles and Gifford team up and offer Cassie a deal for her support: a $100,000 annual allowance for Nan, which Cassie will control. Cassie, worried about what would happen when Nan turns 21 or gets married, insists that Nan marry her son Nicky. Tim overhears the entire scheme.

At his mother's urging, playboy Nicky starts romancing Nan, who is not immune to his charms. Tim becomes jealous and does his best to interfere, so Cassie has him locked in his room. Tim falls through a greenhouse roof after escaping out the window and is knocked unconscious. Groggy, he speaks rationally in the presence of Nan and Nicky. Nan, recalling that Schuyler's irrationality was caused by a childhood blow to the head, hopes that a second blow may have cured him. Dr. Mason allows that it is possible, so Tim decides to remain lucid.

Tim falls in love with Nan, who gets more than she bargained for when she kisses him to show him the difference between brotherly and romantic love.

Then Cassie discovers the truth. She insists that Tim keep up the impersonation, as the inheritance would otherwise go to a charity. After two years, Nan would come of age, and Schuyler could have a staged death. Cassie is confident that Nan would provide for her relations and agrees to drop the idea of Nan's marriage to her son. Noonan tells Nan that Schuyler had lucid periods before, but has always relapsed, and that Schuyler feels his rationality slipping away again. The two men head to Hawaii.

Fortunately, Noonan produces the real Schuyler, who is very much alive and married to a native Hawaiian named Kamamamalua. The authorities finally caught up with him after a long string of arsons. Nan and Tim are reunited.
