When Wall Street investor John Trevor faces bankruptcy, his future son-in-law, George Lathrop, promises to lend him $100,000. However, George has squandered his own inheritance and obtains the money by stealing negotiable securities from wealthy Sam Millington, whose son, Jack, has entrusted him with the keys to the family safe. Meanwhile, John's daughter, Alice, suspects George of having an affair with his ward, Clarita Ortega, and breaks their engagement. Jack Millington discovers both the theft and the reason for it but decides to clear George. He then lends John the necessary capital, buys back the stolen securities, and, by faking an automobile accident, convinces his father that the securities have been in his possession the entire time. George realizes that he loves Clarita, who is actually John's long-lost daughter. Alice finds happiness with an Italian count.
