Katherine is the star of Holly's House, a popular children's television show. Holly herself is a remote-controlled child-size robot. When Katherine is linked to the robot via wires and radio waves, she can make Holly walk and talk like a real person. Lenny, who plays 'Mike the Mailman', has gotten Katherine pregnant and asks her to marry him. But a stressed-out Katherine begins to think Holly is talking to her, and 'Holly' becomes jealous of Lenny and others on the show. Is Katherine going mad, or is something sinister going on?
