Murray 'Boz' Bozinsky (Thom Bray) invites his friends Cody Allen (Perry King) and Nick Ryder (Joe Penny), who are also his business partners in the Riptide Detective Agency, to accompany him to a singles dance. Cody and Nick - a couple of hunky playas/face-men see it as needless but decide to put in an appearance out of respect to Boz.
Nick has a miserable time. Very unexpectedly, Cody meets Sheila (Marta Dubois) the woman of his dreams and they dance most of the night away. He is immediately smitten and she reciprocates. But the promising connection hits a snag when Sheila's mind drifts to thoughts of her twin sister Marcy whom she believes has gone missing.
The next day Nick is far from enthused at the fact that Cody has volunteered the agency to look into it but goes along like always out of friendship. It turns that Marcy, unlike Sheila, is a very bad girl and in trouble with a mean mafioso pimp (Dennis Franz). But if that was all there was to it there wouldn't be much of a mystery.
Cody clashes with Nick and Boz over the meaning of information they uncover. It could be interpreted in ways which shed a very different light on Marcy and her high stakes dealings with her employer. Sheila could be in grave danger. So could Cody just by being with her. Nick and Boz try to have Cody's back but the old bachelor knows he has found Miss Right and guided by that he may be of little help to himself.
I saw Marta Dubois on multiple different shows in the 1980s and 1990s. There was always this air of mystery and complexity in the characters she played that most other female guest stars lacked. On Magnum P.I. she dumped Tom Selleck for a Vietnamese diplomat. On L.A. Law she beguiled Victor Sifuentes then scared the bejesus out of him. On Star Trek: TNG she played the devil. Her performances were always unpredictable but with a sense of fun.
