In coastal northern Australia, CHARLIE, a seaplane pilot, along with his girlfriend KAZ, own a struggling air charter company. Their fortunes change when they receive a last-minute booking from a wealthy businessman JOJI and his wife MICHELLE. But what should have been a fun-filled trip to remember, soon takes a sinister turn when they discover an upturned boat in the middle of the ocean. When Charlie lands the seaplane close to the wreck looking for survivors, it is obvious that something terrible has happened here.
When their seaplane is destroyed in a freak accident, the group are left trapped on a life raft 100 miles from the shore. What follows is a desperate bid for survival as the group try to make it to dry land before they run out of supplies or are taken by the man-eating sharks lurking just beneath the surface.
