Watch Cross-Country Killings Kick Off a 'CSI' Trilogy Online

When a woman is killed in Las Vegas and her body is dumped in Miami, it launches an investigation that crosses over from "CSI: Miami" to "CSI: New York" and wraps on "CSI: Crime Scene Investigation." It is one story, but three episodes. The only constant is that Ray Langston (Laurence Fishburne) moves through all three episodes, searching for a young girl taken hostage as part of a human trafficking operation. "Young women are killed and their body parts are strewn all over the country. That is what keeps my character on the move," Fishburne says.
