Leela, in her last moments of life, recalls a long-forgotten memory: a time in the TARDIS. The Doctor is worried that K9's increasingly bizarre behaviour might become dangerous. He decides to make a new model, little knowing that the fate of all three time travellers has long since been decided.

As Leela recalls the chilling connection between K9's ‘illness’, the Z-nai and the haunted sea fort in which the TARDIS lands, she prepares for her final journey: into the land of her ancestors; the Afterlife.
