From 1768 to 1771, the HMS Endeavour, commanded by the famous Lieutenant James Cook, sailed on a voyage of discovery around Tahiti, New Zealand, and Australia. It didn't end well.

Now, a modern-day tourism company is offering a "luxury" trip aboard a near-accurate recreation of the ship, Endeavour. For a hefty fee, elite passengers can experience history with all the modern comforts. The vacation of a lifetime...until the unthinkable happens, and seven children are stuck aboard the ship, alone and adrift at sea. Rough seas and rations are the least of their worries as they quickly realize the real enemy is each other.
