Coastwatcher

It's 1943, and 19-year-old radio operator Frank Benson is shipped out to an enemy-occupied island in the Solomons with two other soldiers. Their mission is to spy on the Japanese.
In dense jungle they meet a Solomon Islander who says he has information that will shatter Japanese defences. But he could be working for the enemy. What if it's a trap to get them killed? No training could have prepared Frank for this decision. Their lives - and Operation Pacific depend on his next move.
