As the winter ice thaws, Idaho's River of No Return flows, and the people living on its shores navigate the raging spring rapids; the small community hustles to work, so they can survive another season in this rugged and dangerous back country.
A predatory bear stalks a homestead forcing the rancher to aggressively protect himself and his cattle; a jet-boat engine failure in the river rapids puts Buck's operation in jeopardy; a violent storm forces bush pilots to make an emergency landing.
After a rafter goes overboard, a legendary jet-boat captain springs into action to save the man before the river's rapids claim another victim; heavy rains threaten to destroy Aubrey's ranch, and she calls in air support to help save her barn.
With the rapids raging, Buck trains his 8-year-old son to be a jet boat captain; ranch caretaker Aubrey tends to her pregnant mare during a risky delivery; in the skies above, a bush pilot mail drop goes terribly wrong.
Father and son jetboat captains take on Deadman's Rapids; as a storm bears down, scrambling to re-roof the barn, Pete takes a potentially catastrophic fall; felling a massive dead tree puts Ron and Wes at risk from widow makers crashing from above.
With dangerous rocks exposed by low water, Buck must hit high speeds to keep his jetboat out of harm's way; landing solo on a narrow airstrip tests Katie as a pilot; Aubrey plays matchmaker between her reluctant mare and a stud donkey.
