180 days.

An unknown charity donated money to a school called Riverstream high, to send 15 students, picked from ages 14 to 18, to go on a 180 day trip. That's round about half a year. It's a bit long for a school trip, huh?
These 15 students aren't as fortunate as most of the students who attends Riverstream high. They all come from various backgrounds. None of these students can afford to go on holiday so this is theirs for a whole 180 days. Each students are given a list of items to bring along with them including a camp stove, little pots and pans, bedding, an inflatable mattress and lots more.
Once they arrive at Whalers cove, they all get split into 4 different groups. Each group shares a cabin of their choice which contains nothing but 2 tall, wooden, bulky bunk beds.
Events begin shorty after there arrival.
