Seismic is about earthquakes. In Los Angeles. In the not too distant future. It tells the story of a charismatic homeless man with the uncanny ability to predict seismic activity, an underappreciated reporter who somehow always manages to be in the right place at the right time, three Catholic high school girls who should be studying for finals, and a seminarian from Central Africa desperately trying to understand America. Their lives converge and collide in unexpected ways with unintended results.
