Things do not go swimmingly for Speedo-sportin' stud Ben (''Bring It On'''s Bradford) after he has hot sex in the pool with new-girl-in-school Madison (Christensen). Besides being a cellist, Madison turns out to be -- surprise, surprise -- a psycho who stalks Ben and his girlfriend (Shiri Appleby). Unfortunately, the script's biggest shocker is the fact that Ben works part-time as a nurse. Swimfan is so predictable that it's virtually thrill-free. In short, it's all wet.
