Doctor Who - Season 21 Episode 15
Planet of Fire (3)

Sarn prophesy foretells of an outsider who will come to aid the people. Its a role the Master is more than delighted to fill, which finally presents Timanov, the Sarn religious leader, the unbridled support hes sought in his campaign to cull the faithless from among his people. Turloughs secret past, however, is somehow intricately involved in all this, and the reluctance of its disclosure is enough to threaten all friendly ties with the Doctor.
