Trying to track down an episode...

I remember watching an episode of what I believe was The Sentinel. It was about a star beach volleyball player who was kidnapped by a crazed stalker fan, and the main character had to rescue her. Does anyone remember this episode from The Sentinel? Reading the synopses of every episode, I'm now wondering if I was thinking of another TV show. If anyone knows what I'm talking about, it would be really helpful. Thanks!
