The hunt is on . . . for revenge.

It is 1914 and the cocky, incorrigible Flynn Patrick O'Flynn is enjoying his charmed life poaching in East Africa. Flynn enjoys taunting his neighbour, the German military commander Herman Fleischer, who loathes Flynn and is determined to seek vengeance and reclaim his pride.

When young Sebastian Oldsmith joins O'Flynn as aide and apprentice, he's eager to follow in his footsteps and, with O'Flynn's daughter Ruth, the three form an alliance and join the war effort, helping the British Naval forces in the hunt for a German warship.

But the war is exactly the excuse Fleischer has been looking for to exact his revenge. Soon the hunt is on and O'Flynn realises that war is far from a game . . .
