Swimfan (2002)

His biggest fan just became his worst nightmare.

Ben Cronin has it all: the admiration of his many friends, a terrific girlfriend, and he's on the fast-track to an athletic scholarship. Ben's rock-solid, promising future and romance are turned upside-down with the arrival of Madison Bell. Madison, the new girl in town, quickly sets her sights on the impressionable Ben. While their first few meetings are innocent enough, the obsessive and seductive Madison wants more ... much more.
