Leading up to the National Middle School Tennis Championship, the participating club members travel to a remote island as part of a training camp to develop their mental fortitude.
But, the day before landing on the island, the team's boat is caught in a storm, and runs aground on the rocks.

Also aboard were the captain's daughter and her friend, who share a lifeboat with the team as they are forced to abandon ship.
However, the tidal currents separate the team from their teachers and the captain, as the lifeboats are swept away.

Struggling ashore, the team decides to make for the campgrounds, but all they find at the isolated camp are sparsely equipped log cabins.
Now, with nothing but the hand tools, lamp, and other few supplies they manage to collect, it's up to them to find the food, water, and fuel they'll need to survive.

This is the story of your unexpected, unforgettable survival adventure.
