The 1986 television series is set seven years after the events of the 1983 mini-series. Stephanie Harper, Australia's richest woman, is happily married to her plastic-surgeon husband. Her two children are now young adults, involved in the Harper 'empire' but with their own problems. The release of Jilly Stewart from prison starts a dramatic chain of events.
