Pacific Blue - Season 3 Episode 8 Matters of the Heart

Following a violent robbery at a cafe, the Bike Squad discovers an abandoned baby. In searching for the mother, they find that the child was part of a black market baby-selling scheme. Cory goes undercover as a pregnant woman to find the baby seller, unprepared for the rush of maternal feelings the case will uncover for her. The cafe robber is arrested, but dies of a heart attack while in lockup. When it's learned that the robber was also a bike racer taking a powerful ""performance-enhancing"" drug, T.C. goes undercover to find the sellers, who operate out of a local bike shop, and befriends a guy hooked on the drug.
