What Attack Girls' Swim Team Versus the Undead is
Poolside January afternoon. A single lane rope bobs in chlorinated silence. The inoculation turns bite victims into wriggling, sex-crazed flesh-hounds. Teachers juggle heads and students drown in chlorine while in swimsuits. Splatterpool slasher, but all wet work.
