Garrez, the mail carrier, writes his wife a note to the effect that he has to deliver $15,000 in cash across the American border line and that he desires her to disguise herself in men's clothing and meet him on the morrow by the Two Oaks. Just after Garrez leaves on his trip the postmaster receives word that the insurgents being active, a guard should accompany the carrier. The postmaster thereupon sends out a guard to overtake him. In the meantime Garrez meets his wife and gives her the money, telling her that she must bind him to the tree. She does so and just as she has finished the guard comes into sight. The deed has been seen by Rosa, who acts the part of a good Samaritan toward Juanita. Garrez tells the guard that he has been held up and robbed by a bandit. Later Garrez rejoins his wife and finds that Rosa has been a witness. He attacks her and binding her arms and legs, throws her down a bank into a stream. She is drowning helplessly when found by her aged father. She tells all and Garrez and his wife are brought to justice.
