We open at a cabin in Lake Manitoc, Wisconsin. Inside, a skinny blonde girl in a warm up suit greets her father and brother, the latter of whom informs her that she shouldn't work out so much because guys don't like buff girls. How about GO FUCK YOURSELF, I WORK OUT FOR ME. She informs him that girls don't like guys who still live at home before she heads out the door. (S: BURN.) Her dad tells her to be careful.
Cut to her standing in a bathing suit next to the lake. We get a weirdly far away shot taken through some bushes as she dives in. We follow her underwater for a second, then she surfaces. She looks to the shoreline as if she's heard something, then swims for a few moments and does a tumble turn. Which I really don't see the point of because there's no wall to push off.
