Ella Peterson spends her days in the basement of Susanswerphone, her cousin's answering machine company. Fortunately for Ella, her existence on the switchboard is made bearable by the connection she establishes with her customers and the different identities she brings to each of them: an arrogant Parisian to answer calls from a French restaurant; as Santa Claus to convince a young boy to eat his spinach; and as a warm mother figure to comfort the charming playwright Jeffrey Moss, whom Ella has fallen in love with.
She wants to help him write her play but is intercepted by the police who accuses her company of being an escort service. It does not help, when she accepts that J. Sandor Prantz, a con artist, installs his record company, "Titanic Records" (in reality, a facade for a ring of play), in her office.
Will Ella manage to save the company and her love?
