The film describes Margo's life since The Good Life finished. Unlike the earlier Life Beyond the Box: Norman Stanley Fletcher, most of the actors, except Moyra Fraser, from the original series did not take part and appear only in archive footage. The film also includes celebrity cameos from Richard and Judy, Max Clifford, Raj Persaud, John Sergeant and Judith Chalmers.
