The Cartmel Masterplan is a fan name for the planned Doctor Who backstory developed primarily by Andrew Cartmel, Ben Aaronovitch and Marc Platt, by which they intended to restore some of the mystery of the Doctor's background that had been lost through revelation of the existing backstory. Although hints were dropped in the last two seasons, the proposed revelations never materialised on screen as the programme was not renewed for another season in 1990.
