Charles Brailing has grown tired of married life and wants to travel the world. After a night at the bar, he confides in his friend Tom that he has purchased a robot clone from a company called Marionettes, Inc. The marionette looks and sounds exactly like Charles and he plans to leave it at home with his wife so he can travel to Rio. He keeps it locked in a tool chest in the basement when he is home and summons it with a special whistle.
When Tom sees the robot in action, he is so impressed that he decides to purchase one of his own in order to escape the constant doting of his overly affectionate wife. Charles gives him the company's business card, but when he gets home, Tom realizes the woman in his bed is a marionette. His real wife has left him. Meanwhile, Charles is confronted by his marionette, who resents being locked in the chest and has grown fond of Charles's wife. The robot eventually overpowers Charles, takes his ticket to Rio and locks him in the chest. The marionette enters the bedroom and romantically kisses Mrs. Brailing's hand, now permanently assuming Charles's identity.
