The series follows Stone (Jonny Lee Miller), a San Francisco lawyer who begins to have hallucinations (such as a George Michael soundtrack that only he can hear and getting dive-bombed by a World War I biplane on a busy San Francisco street) which leads him to two possible conclusions: a potentially fatal brain aneurysm, or the chance that something greater is at work. His visions lead him to accept cases with little monetary gain but a lot of moral goodness; Stone also predicts an earthquake that hits San Francisco. Other such events occur throughout the course of the series, but the series was cancelled before reaching a coherent conclusion.
