表姐，妳好嘢！

Cheng Shih-Nan is a Mainland inspector who journeys to Hong Kong with her assistant and cousin Hsiou Sheng to deliver a ruthless criminal. But the bad guy escapes, meaning Shih-Nan and Hsiou Sheng are now stuck in capitalist Hong Kong for an extended stay! A flag-waving supporter of the Communist Party, Shih-Nan marvels at the “decadent” lifestyle of her Hong Kong counterpart, Inspector Wu Kei Kuo. But despite the culture clash, the two disparate cops find the common ground they need to dispense justice – and even discover something akin to romance! But will the Party approve?
