In 2004, Yates's two-part drama "Sex Traffic" was broadcast on Channel 4. It won eight BAFTA Awards including Best Editing for Mark Day, who regularly worked with Yates on many of his television projects and short films. Day commented on his collaboration with Yates saying that "we are very good friends because we have spent so much time together". He also said, "David shoots in a similar style from piece to piece, although this wasn’t quite as frantic as "State of Play"." Yates was nominated for another Directors Guild of Great Britain Award for his direction of "Sex Traffic" and won his second BAFTA for Best Drama Serial at the British Academy Television Awards. Being a British-Canadian production, "Sex Traffic" gained four wins at Canada's annual television award ceremony, the Gemini Awards, including Best Dramatic Mini-Series. Spanning across two parts, the three-hour-long drama reveals how the trafficking of young women into slavery is a big business which operates throughout Europe; both parts were acclaimed for their "shocking" portrayal of such a sensitive topic.
