Synopsis

After travelling backwards, forwards and backwards again in time, Martha Jones has returned home. However, before the Tenth Doctor can bid farewell to her, he hears Professor Richard Lazarus announcing that he'll "change what it means to be human." What could this mean? And could it lead to something far more dangerous than a simple scientific failure?
