First part of a feature-length / two-part story. Starsky and Hutch are loaned to the Las Vegas Police Department to snare a serial killer that has strangled a string of chorus girls. But the pair don't realise that they've been chosen for the case on more than merit alone. The prime suspect is an old high-school friend of Hutch's. While tracking down the killer, Starsky starts seeing an attractive show-girl–who could possibly be the killer's next victim.
