Carla works in a real estate office and has a hearing problem. Carla makes the acquaintance of Paul, a small-time criminal who has just been released from prison on parole. Before long, it becomes obvious that Paul is having an influence on Carla's normally stable nature. Carla and Paul's actions go from malicious to seriously criminal when Paul hatches a scheme to rob a nightclub owner to whom he owes money -- a scheme that involves Carla's keen skill as a lip reader.
