This episode served as the pilot for the spin-off series CSI: Miami, with David Caruso making his first appearance as Horatio Caine, Miami counterpart to CSI's Gil Grissom (William L. Petersen). It all begins when Las Vegas' former chief of detectives is killed execution-style after a party at his home. In addition, the dead man's young new wife and their seven-year-old daughter are missing. Ultimately the girl is spotted near Miami, obliging the Vegas CSI team to work hand in glove with Horatio Caine and his colleagues. Other soon-to-be regulars of CSI: Miami introduced herein are Emily Procter as Calleigh Duqesne, Adam Rodriguez as Eric Delko, Khandi Alexander as Alexx Woods, and Rory Cochrane as Tim Speedle.
