In a tropical jungle, Jack wakes up in agony. He is bruised, bloody and disorientated. A terrible memory flickers across his face. He winces back the pain and begins to run through the trees, reaching a beautiful beach.
He hears sounds – people screaming. He rounds a bend to find the wreckage of a plane crash, surrounded by survivors in shock. His doctor’s instincts kick in - and he runs to help those he can, rallying others to his aid.
After treating the injured, the able-bodied survivors rescue what they can from the fuselage, but the cockpit, where the radio transceiver is kept, is missing.
As darkness falls, a monstrous howl rings out from the forest. The tops of the trees shake, but eventually whatever is making the sound goes away, leaving the survivors marooned, exhausted - and now terrified.
The next day, Jack and Kate head into the jungle to look for the cockpit, accompanied by Charlie. Struggling through a torrential rainstorm they find the wreckage, where the apparently dead pilot regains consciousness.
The terrifying howls begin again - this time just outside the cockpit. And when the pilot crawls out to see what is making the sound, he is snatched up by a mysterious force.
Jack, Kate and Charlie run for their lives, but the pursuit ends as abruptly as the rainstorm. Retracing their steps, they discover the body of the pilot hanging from the top of a tree. They stand there, wondering what could do something like that...
