Not Alone.

A sophomore class is taking a filed trip to a beautiful place within the woods, they would be staying in a cabin resort for two weeks, the last class that was sent to this trip, was the rambunctious class...they were too crazy, weren't following the rules, doing inappropriate things that kids their ages should not do, and just in general, a bad class, so they within three days of the first week, were to be sent home, along with the other class, which did nothing wrong.

But...

In the way back, driving through the unfamiliar and eerie woods, something needless to say happened, and worse enough the school was never informed of the early arrival since the teachers in no way could contact due to lack of internet connection...
