Silent Witness - Season 20 Episode 9

Nikki travels to Mexico following the disappearance of Lyell Centre intern Luisa in a suspected carjacking. After realising that the police are making little to no effort to find Luisa's body, Nikki teams up with project manager Dr. Eva Vasquez in an attempt to finally discover the truth. Back home, Thomas decides to send Jack to Mexico with one strict instruction - to bring Nikki home safely. However, he soon finds himself drawn into the case as Nikki and Eva find a mass grave containing six bodies. As Federal Police capture a cartel leader known as 'The Vulture' for his suspected involvement in the mass murders, Eva receives a stern warning to stay away from the case. And when Nikki later disappears, Jack realises she could be the next victim.
