'Mud, Sweat and Tears: The Road to the Rugby World Cup' will air on STV at 8pm and will include exclusive behind-the-scenes footage of players and their families.
The documentary is a co-production by MediaCom’s specialist content division MediaCom Beyond Advertising and STV.
It was produced by STV's Mick McAvoy and MediaCom Beyond Advertising's Francis Baker.
Nick Cohen, managing partner of MediaCom Beyond Advertising, said: "This documentary partnership is a wonderful example of the way we see brands, TV companies and media agencies coming together in future to create high quality content and programming."
RBS, which recently became the new principal brand partner of Scottish rugby, announced in June that it is reviewing its £50m media planning and buying account for its retail business, currently handled by MediaCom.
