Jack Nelson, a clerk in the office of Henry Winters, a businessman, is in love with Neva, his employer’s daughter and wishes to marry her. Neva’s parents object but she is more than willing. Jack writes a letter to Neva and asks her to elope with him that night. Winters writes a letter to his brokers and asks them to buy all the K.T.O. stock for him they can get. He gives the letter to Jack to deliver. Jack starts on his errand and goes around by Neva’s to deliver her letter via her young brother. He meets Neva instead and makes arrangements to elope with her that night. He goes to the brokers’ office and delivers Neva’s letter in mistake for the one Winters had written. That night he goes to Neva’s house to get her, and sees a burglar clambering into Mrs. Winters’ room, from a ladder. He follows the burglar into the house and is captured by the intruder and locked in a closet. The burglar also robs him, taking the letter that Winters had written to his brokers. Neva looking out of her window, sees Jack enter her mother’s room and rushes down to the foot of the ladder to warn him. The burglar comes out and is promptly embraced by Neva, who thinks he is Jack. The burglar runs and is pursued by a policeman. In his flight he throws away the letter and other things he had stolen. The letter goes through the open window of Winter’s office and lands on his desk. In the meantime, K.T.O. stock takes a sudden big drop and Winters remaining at his office late faces certain ruin. He opens the letter and finds that his brokers have never received his letter. He is saved from financial ruin. A messenger arrives from his brokers bringing Jack’s letter to Neva. He rushes home in a rage to prevent the elopement and finds that Mrs. Winters has just discovered Jack in her closet. Explanations follow and the young people eventually are forgiven and permitted to be married.
