It's the eve of the first day of high school for 14-year-old Ethan and his buddies Benny and Rory, and they're ready to shed their Star Trek pj's and geeky image and finally be cool! Ethan and Benny baby-sit his 8-year-old sister Jane and mark the moment by making the ice cream sundae to end all sundaes. When Jane wanders out to the road by herself and almost gets killed, Ethan's parents slam him with the worst punishment possible - a babysitter for all of their future Friday night "date nights". As if that's not enough to ruin a freshman's already precarious image, Ethan's about to find out that his 16-year-old "babe-o-sitter," Sarah, is not just the hottie he's crushing on at school - she's a fledgling VAMPIRE! Ethan, Benny and Rory get dragged into Sarah's mission to stop her blood-sucking ex-boyfriend Jesse from taking over the town - and they begin to realize that their sleepy little town of White Chapel is holding some dark and spooky secrets. And that they may just have some secret powers of their own. As Sarah's BFF Erica and the rabid fans of The Dusk Chronicles (those very popular movies where gorgeous vampires try not to eat people) plan for the big Dusk 3 premier and Jesse plans his ultimate vengeance on White Chapel, Ethan realizes that he, Sarah and his friends may be all that stands between life as they knew it - and the end of the world.
