Dolphins invent a new mass fishing technique, soon threatening the world’s fish population with total collapse. Humans must somehow convince dolphins not to repeat our mistakes.

Together in tandem, humans and dolphins compete across the globe for remaining fish populations. The tensions eventually spark terrible wars between humans and dolphins. Children afraid of beaches are reared for two generations. Due to decades of strain and war, the last of the global fish population finally collapses, as well as most of the Earth's ecological systems. The remnants of human and dolphin kind cling to the wreckage, unsure of their future, but finally united under survival.
