Have you ever eaten sushi? If so, the phenomenal growth in demand for sushi has come at a cost: overfishing has led to depleting fish stocks, which in turn has threatened the balance of the ocean's ecosystems.

This timely documentary - winner of the Special Jury Prize at the 2011 Seattle International Film Festival and the Audience Award at the 2012 San Francisco Green Film Festival - poses some important questions that all sushi lovers should give thought to before placing their next order of sushi.
