ER costar Ming-Na is cast as Li Mei Nu, an immigrant woman in search of her missing sister Jiao Wu. The authorities are also interested in catching up with Li Wu, who has apparently abandoned two of her daughters in a squalid apartment. As the SVU detectives pursue the case, it becomes clear that the missing woman was being persecuted by an alien-smuggling gang which uses its "customers" as sweatshop workers and sex slaves. Unfortunately, none of the gang's victims are willing to cooperate with the detectives--especially after Li Mei is savagely beaten on the orders of a corrupt customs attorney. ~ Hal Erickson, Rovi
