A prodigious Chinese swimmer kills himself on the eve of the Beijing Olympics. Days later, a champion weightlifter suffers a fatal heart attack prior to competition.

Detective Li Yan senses a conspiracy surrounding the fatalities, and finds a female athlete willing to talk. But she will only trust one person: Li's fiancée, Margaret Campbell.

When Campbell's contact herself vanishes, the gun is fired on a race against time. And Li must now outrun, and outwit, an enemy bent on pushing him beyond endurance.
