This film investigates the parallel stories of collapsing Pacific salmon populations and how biologists and engineers engage in audacious experiments to shore up their numbers. Each of our efforts to save salmon has involved replacing their natural cycle of reproduction and death with a radically manipulated life history. Our once great runs of salmon are now conceived in laboratories, raised in tanks, driven in trucks and farmed in pens. The program goes beyond the ongoing debate over how to save an endangered species. In its exposure of a wildly creative, hopelessly complex and stunningly expensive approach to managing salmon, the film explores possible paths to salmon recovery.
