This curious story seems even odder when you know it came from the pen of Western writer Zane Grey. Mercedes McDonald (Claire Adams) is the niece of the Countess de Elberca (Rose Dione). The Countess and Don Felipe de Cristobal (Frank Leigh) both want to arrange a marriage between Mercedes and Don Felipe's nephew, the Duke of Othomo (Bertram Grassby). The girl, however, is already engaged to Sandy Buchanan (Carl Gantvoort), a young engineer who is working on the Countess's oil fields. To get Buchanan out of the way, the Countess fires him and Don Felipe hires a hit man, Pedro (H. Gordon Mullen), to kill him. But nothing Pedro does works -- Buchanan always manages to escape harm. Finally, with the help of some circus people camping nearby, Buchanan forces Pedro to confess by sticking him in a cage with a tiger. Before he is reunited with Mercedes, the young American finds himself at the mercy of a mob of peons. Mercedes comes to his rescue by releasing the circus animals from their cages.
