The 90-minute documentary by filmmaker Ali Tabrizi starts out as a nature documentary trying to understand whale stranding, but soon turns into a journey uncovering the effects of the commercial fishing industry. With hidden cameras and filming in dangerous locations, the documentary tries to expose the illegal fishing markets which have a deeper, hidden system of corruption, slavery and fraud, involving the big industry names and government backup. Seaspiracy travels from Asia to Europe to the U.K making new revelations about the industry while maintaining a sense of urgency.
