Tastes Like Candy 2: Viciously Sweet

Five years ago, a group of teenage girls entered the Poison Apple Halloween Carnival for a scavenger hunt, and all but one died at the hand of a masked killer. Now, a copycat killer has emerged and is using a familiar cotton-candy-coated playbook to pick off a new group of girls one by one.
Meanwhile, the Scavenge's lone survivor—still haunted by ghosts from the past and unable to move on from her loss—begins receiving disturbing text messages, seemingly from beyond the grave. When someone from home contacts her for help, she realizes that she must return to the carnival to warn the new girls and stop the original killer's protégé, or they may suffer the same fate as the victims in the last Senior Scavenge.
There's just one problem: According to the people of Belldam, the Senior Scavenge never happened.
