A trailer for the TVB 2012 Sales Presentation trailer was shot earlier during October 2011 and the Sales Presentation was aired on 17 December 2011. The trailer featured Roger Kwok, Michael Miu, Kevin Cheng, Kate Tsui and Joyce Tang. Kwok portrayed a triad mole sent to the Narcotics Bureau (NB), Miu portrayed an undercover cop from NB, Cheng portrayed an NB officer, Tsui portrayed a pregnant drug dealer and Tang portrayed Miu's wife. Kwok, Cheng and Tang were unable to film due to conflicting schedules. As a result, Elaine Ng, Raymond Lam and Ella Koon were added.
