Chase's peaceful afternoon at anchor is abruptly shattered when an old friend appears, telling him of a missing treasure hunter. Rikki Talens ventured upriver on a wild goose chase, and now she has vanished without a trace.

Determined to find her, Chase pulls up anchor and begins his search. As he ventures further upriver, Chase finds himself in the midst of a small army of men guarding something suspiciously in the woods.

What could be so important that they would kill to keep it hidden? He must continue forward, no matter the cost, to save Rikki.
