Undertow is a better than average porn flick. It features something rare indeed for the jizz biz good acting and a decent plot. Unfortunately, the cast doesnt put as much work into the sex as they do into their dialogue. Steven St. Croix, arguably the best actor in the industry today, is host of an underground TV show titles Thrill Kill Zone. The show deals with street racers. Because of his involvement in that sport, he is recruited by Dale DaBone to be an informant for the FBI as the agency tries to get the goods on Irish terrorist Evan Stone, who is also involved in the illegal races. This may be the first porn movie in history to include not one, but two, sword fights on a beach. No, not those kind of swords; real Japanese fighting swords. Theres pretty good editing as Evan and Steven battle on the sand and look convincing while doing it. But we watch porn for sex, and there just isnt enough heat among the performers to make it very interesting.
