The bad news in Undertow (1996) is that Lou Diamond Phillips is a traveler who’s unlucky enough to get stranded with Willie. The good news is that Willie is a sexy young gal played by luscious Mia Sara. And the worst news is that she’s married to psychotic hermit Charles Dance. This tense thriller crams plenty of intrigue into a three-person drama. Thankfully, the plot is helped along by Mia enjoying a shower with lucky Lou.
