In the blink of an eye, a fisherman's idyllic vacation turns into a terrifying struggle for survival. One moment he is fly fishing a remote river in the icy mountains of New Zealand and the next, he finds himself on the wrong end of a manhunt.
As he tries to contend with starvation and the harsh and uncompromising wilderness, the fisherman must also deal with killers on his trail and the turmoil within his malnourished and frightened mind.
Meanwhile, Auckland detectives are hunting a shadowy criminal syndicate suspecting it is behind a rash of deaths related to the manufacture and distribution of crystal meth (ice), including that of an innocent teenage schoolgirl. The detectives' investigation and the fisherman's ordeal collide in the rocky, forested wilderness, where a brazen Maori police officer must salvage justice from lawlessness.
